28 + 29 October 2017


DATE: 28 + 29 October 2017

LOCATION: Langdale, Lake District

The 50th Anniversary race is now full with 2000 competitors entered. We will now operate a reserve list for anyone still wishing to enter. Please enter your details in the form and we will be in touch if a place becomes available. 

The extreme two-day race, held at the end of October, started in 1968 to combine fell running, orienteering, hill walking, trail running and an overnight wild camp. With an ethos of self-reliance and endurance, competitors are at the mercy of the elements…and their own decisions.



In 1968 Gerry Charnley created a 2 day mountain test.  The event combines navigation, endurance, teamwork and a wild overnight camp. The Original Mountain Marathon is considered to be the event that all adventure races descended from. See the history of the OMM here.


THE OMM is the only civilian event approved for use as a training opportunity for British Military personnel. See event details below.
Defence Instruction Notice 2016DIN07-124

ELITE Course – up to 120km + approx 4000m ascent

The ELITE CLASS course is recognised by professional athletes around the world. The combination of terrain, distance and conditions make it a very serious undertaking. In 2016, 25 countries were represented including Team GB Orienteers, professional athletes & elite military forces.   This is not for the faint of heart so check out other OMM courses and Lite events before thinking of this! View previous results here.


Your previous experience and sound mountain judgement will decide what kit you should be wearing and carrying.

In order to conduct the competition on a fair and equal basis for all participants, and ensure safety, it is necessary to apply rules governing a competitor’s conduct, clothing and equipment. These rules, which are set out below will be STRINGENTLY enforced.  Anyone found to be in breach of these rules will be automatically disqualified from the current event and may be banned from future events.

  1. THE GOLDEN RULE: Once registered, competitors must report to the Event Centre to return their scoring tag by 16:30 hours on the Sunday whether they have completed the course or not.  Without it the team is deemed missing and will be searched for!  Please note that if you fail to return the tag before leaving the event area you may be liable for any rescue costs incurred.
  2. Elite Class, all competitors must be 18 years old on the date of the competition and at least one of each team must be a minimum of 20 years of age. In other classes A,B,Combined and Score, all competitors must be 16 years on the day of the competition and at least one of each team must be aged 18 years or older.
  3. Winning teams in each class are not eligible to compete competitively in the same class in future years (this excludes Long Score and Elite).
  4. A minimum amount of Mountain Experience, navigation and outdoor skills are essential and details must be provided on the entry form.
  5. The event is for teams of two and pairs must maintain contact (close enough to communicate by voice) throughout the competition. Both team members must visit the control sites together carrying all their equipment. i.e. the team must be in possession of both rucksacks at all times. If one member of the team cannot continue the whole team is retired – The only exception is in the case of an emergency, when competitors must exercise their own mountain judgement as to the appropriate action to take, including but not limited to leaving a partner in a warm safe environment to seek help from others.  The map provides an emergency telephone number and mobile coverage is available in most of the higher areas.
  6. Out of Bounds areas and compulsory crossing points are marked on the competition map and must be respected.
  7. Teams must carry or wear all the equipment and clothing on the official kit list. This is the absolute minimum for safety and survival. The equipment check list must be completed, signed and presented at registration.
  8. No dogs are permitted in the competition area.
  9. Competitors must not seek to obtain unfair advantage by searching for courses or inspecting the competition area before the event.
  10. GPS devices (including mobile phones) may be carried throughout the event but must not be used for navigation.  Any team found using their mobile phone or other electronic device for communication or navigation purposes, except in the case of emergency, will be disqualified from the event.  This includes at the overnight campsite.  We rely on the integrity of our competitors to follow this rule. (unless we remove all electronic devices from every competitor there is no other way for us to enforce this).
  11. Competitors who, in the opinion of the organisers, act in such a way to bring the event into disrepute or unnecessarily endanger other competitors or race officials will be disqualified and may be banned from future events.
  12. Competitors must permit the examination of their equipment by race officials at all times.
  13. On completion of the course all competitors must still be in possession of sufficient rations for an emergency.
  14. No open fires permitted anywhere on the course or at the Overnight campsite.
  15. At the mid-way campsite, no unnecessary noise after 22:00hrs.
  16. Start times for both days, overnight course closure times and final day two course closure times will be printed on the event details and must be clearly adhered to. Teams failing to finish within the course times may be disqualified or may be allowed to continue but marked as ‘Timed Out’ at the Organiser’s discretion.
  17. OMM Ltd reserve the right to use any digital media captured at the event for promotional/marketing purposes.

The OMM aims to offer a range of courses that supports movement up and down the scale of difficulty and nature of challenge.  The score courses are the best option for those who want the flexibility of being able to choose the distances that they cover for the duration of the event combined with a wider range of navigational choices over the weekend. The Linear courses offer a different set of challenges both intellectually and from a competition perspective.

This year we have made changes to the linear courses available so please take the time to read the course details on this page.

There will now be 7 courses in total –  3 linear (time based competition), 3 Score (points based competition) and a combined course (time and points based).

Below you will find details of each course to help you decide which challenge is the one for your team.  The distances and elevation gains are only a guide. As the terrain, going, vegetation (and numerous other factors) change every year, accordingly so do the course specifics. We plan the courses based on the expected average time of the top 5 teams respectively.

Please ensure you complete the ‘previous experience’ section on your entry and we may contact you to discuss your choice of course if we have safety concerns.  We recommend the Short Score course for first time OMM competitors.

The actual courses are only disclosed to competitors on issue of the map at the start line.  A separate map is issued each day. Controls locations are marked with a circle and the legend will give control descriptions and the time each control closes.  We work very closely with HARVEY maps to produce the best possible mapping for the event.  Blank maps will be on display in the refreshment area on Friday evening and Saturday morning.


Linear are timed navigation courses where specified checkpoints must be visited in order. Teams are free to choose their routes between checkpoints.  Fastest time wins.

Due to the lower numbers wishing to take part on certain courses the decision has been made to combine the previous A and B course (now to be known as the A course) and change the name of the D course to B course and finally to avoid confusion the C course shall now be called the Combined Course.


Approximately 85km (straight line distance) over two days with 4000m + ascent. This is a timed navigation course where specified checkpoints must be visited in order. Competitors are free to choose their route between checkpoints. Winning times usually around 12hrs. It is advisable to have significant previous race experience at a suitable level, e.g. the A Course or Long Score before entering this class.


Approximately 65km (straight line distance) over two days with 3000m + climb. This is a timed navigation course where specified checkpoints must be visited in order. Teams are free to choose their route between checkpoints. The winning time is usually in the region of 11 hours. In order to compete on this course we strongly recommend previous race experience on the B Course or a similar event.

B COURSE (previously the D course)

Approximately 45km over two days with 2000m ascent. This is a timed navigation course where checkpoints must be visited in order. Teams are free to choose their route between checkpoints and the winning time is usually around 8 hours. Some previous experience required in navigation and mountain terrain with a basic level of fitness.  We recommend that those that are new to the OMM enter one of the Score courses as these give you more flexibility with the distance and time you spend on the hill each day.


Score courses are fixed period competitions where teams accrue as many points as possible in the time allowed.  Checkpoints are assigned points values based on location with competitors free to choose routes for the highest score. These courses test navigation ability and are as physically as challenging as you choose to make it as you do not have to stay out on the hill for the whole time allowance. Points are deducted for being outside your allocated time limit at a rate of 2 points per minute or part thereof. These course are easier to complete than Linear but very difficult to do well competitively due to the increased amount of planning required.


Time limit of 7 hours on day 1 and 6 hours on day 2, significant hill experience and fitness is required.


Time limit of 6 hours on day 1 and 5 hours on day 2, to be competitive significant hill experience and fitness is required.


Time limit of 5 hours on day 1 and 4 hours on day 2.  This is the course we’d recommend for 1st time competitors or those wishing to take a more relaxed approach to the competition.  You will still need to be able to read a map and use a compass.


The Combined Course approximately 45km over two days with 2000m ascent.  This is a timed navigation course combining linear and score checkpoints.  Fastest time wins.  Teams visit a set number of checkpoints, e.g. 10 in total, of which 5 may be compulsory and the other 5 selected from several options on the hill, i.e. there will be more than 5 additional checkpoints on the hill. Expected winning time is around 9 hours.

Still unsure which course to enter? Contact and ask for advice.



It is no longer felt necessary for all competitors to bring their packs to the registration. However it is still considered vital for kit checks to take place, so random kit checks will take place at the start, overnight camp and at the finish. Random checks will include everyone and not merely the high ranking finishers.  At event registration you will be required to sign the OMM Kit Check and Declaration form which can be viewed and downloaded here.


Each individual and team is responsible for being properly equipped for two days unsupported racing in exposed terrain at the end of October.

This list should be seen as a minimum requirement only. Check the weather forecast, your previous experience and use sound judgement for the kit you should be wearing and carrying. The organisers reserve the right to disqualify any competitors who, in their opinion, do not have the necessary kit to survive in an emergency situation. Cotton clothing is not suitable.  


  • Taped waterproof jacket with hood
  • Taped waterproof trousers
  • Clothing suitable for mountain running and walking
  • Spare base layer top
  • Spare full leg cover
  • Warm layer top
  • Hat, Gloves & Socks
  • Footwear designed for trail and fell use
  • Head torch capable of giving useable light for a minimum of 12 hours
  • Whistle & Compass
  • Map (as supplied)
  • Insulated Sleeping bag
  • First aid equipment
  • Pen/pencil and paper capable of being used in wet conditions
  • Survival bag (not a sheet)
  • Rucksack
  • Emergency rations
  • Water carrying capability

Spare warm kit and insulated sleeping bag must be waterproofed (i.e. in a drybag)


  • Cooking equipment including stove with sufficient fuel for duration of the race, plus some spare for emergency use, left at the end of the event
  • Tent with sewn in groundsheet
  • Food for 36 hours for two people


The competition has safety designed into it, provided that competitors follow some basic rules on their conduct throughout the two days. Teams should have all the necessary equipment for them to withstand a night on the hills in the most adverse of weather conditions. The requirement for teams to stick together at all times is an essential ingredient of safe conduct. Do not press on beyond the point where one team member is beginning to suffer from exhaustion or the first signs of exposure.  Do not go for too long without eating, particularly later in the day as you begin to tire. Always wear sufficient clothing and waterproofs to keep warm and dry.  

If in any doubt of your ability to reach the official overnight camp before the designated time limit, you should find a suitable site on the hills and camp independently for the night. WHEREVER POSSIBLE YOU SHOULD CONTACT THE NEAREST MARSHALL OR THE EVENT HQ (IF MOBILE SIGNAL AVAILABLE) OR ANOTHER COMPETITOR TO INFORM THEM THAT YOU WILL BE STAYING ON THE HILL THAT NIGHT.

Knowing your own capabilities, being prepared to look after an ailing partner, not pressing on regardless: these are some of the essential components of safe hill-craft.  If you are staying out for the night, if possible, please contact the emergency number on the map to let the HQ know.

  • EXPERIENCE – All teams are vetted for experience and if necessary we use our judgement to reallocate teams to a more appropriate class or deny them entry.
  • EQUIPMENT – the list of compulsory equipment is the essential minimum and entrants must use their judgement to increase this according to conditions.
  • TEAM WORK – Remember this is a team event and your partner is your first point of aid in case of trouble. The buddy system is invaluable for checking hypothermia.
  • MOBILE PHONES – mobiles are allowed to be carried but may only be used for communication in an emergency and after retiring from the event. If you decide to use whilst still in the competition you will be retired for doing so (this includes the overnight camp on Saturday).
  • ELECTRONIC PUNCHING – Sport-Ident electronic punch systems verify which teams have visited any particular control and, as such, have a significant role in locating missing teams. The related software is specially modified to help rapid visual identification of who is ‘still out there’.
  • SOUND MOUNTAIN JUDGEMENT – Never allow the pressure of competition to override your sense of SMJ (Sound Mountain Judgement) at any time. Remember, every team is different and has its own level of skill and endurance. The decision to start, or to pull out, is yours alone and doing so would be an example of exercising SMJ as a team.
  • On Sunday it is vital that you make contact with the Event Centre if you are unable to get back by 16:30 hours. If you do not do so you will be the instigators of a Mountain Rescue Incident. Pitching a tent on the hill Sunday is only acceptable in the case of genuine emergency.

You will be notified of your start time prior to the event in the final Event Programme.

We now prioritise early start times to category teams (ladies, vets, mixed and family teams). Then by date of entry.



There will only be one start location.  The route to the start on Day 1 will be signposted from the camping field.  Please ensure that you leave enough time to get to the start.   There will be limited toilets available at the start.

Start Times Day 1

From 08:00 hours for all classes except Short Score (09:00 hours).

Map Issue.

All competitors will be issued with a map (2 per team) as you approach the start. This will be overprinted with your course and control descriptions. The maps will be waterproof. To ensure the start area does not get congested please move away from the start before beginning your route planning.

The start line

Each team will be allocated to a time window during which they will be called forwards to start.  Your time will start from when you punch your tag in the start box, however please note if you fail to start within your allocated window you will have to be fitted in at the next available slot, which may be some time.


Both members of a team must finish together – failure to finish as a team will lead to disqualification.  Take care to visit the last controls on both days. This is a common mistake leading to disqualification.

Immediately after finishing on Day 1, follow the taped route to the download stations where you will dip your tag and be given a printout showing the controls visited, with points and split times. Please move away from the area THEN check your printout. If anything is wrong or you need to report having to punch manually, proceed to the enquiry point further down the line. Make sure you keep your tag on for use the next day. Before you leave the finish area please ensure that you clear your tag.

All competitors wishing to start on Day 2 must:

  • Finish Day 1 together, having correctly completed the Day 1 course by 20:00 hours.
  • Have camped in the official campsite overnight.
  • Not broken any of the competition rules.

Ad hoc teams of Day 1 finishers may be allowed to start on Day 2 as Non Competitive at the discretion of the organisers.


Anyone retiring at the overnight campsite must make their own way back to the Event Centre/Day 2 Finish. Transport is not provided except in the case of serious injury. Teams who retire on the first day without reaching the overnight camp will be presumed to have independently camped for the night.

Kit Checks

Spot checks on equipment will be carried out at the overnight camps.


Only the official campsite toilets should be used and no rubbish should be left at the site.

Please boil all water.

The overnight camp/s are out of bounds to everyone other than competitors and race officials.


Your Day 2 start window will have been printed in the Event programme and will also be on the printout you receive after you have downloaded your tag at the end of Day 1.

As for Day 1, each team will be allocated to a time window during which they will be called forwards to start.  Your time will start from when you punch your tag in the start box, however please note if you fail to start within your allocated window you will have to be fitted in at the next available slot, which may be some time.

Teams finishing after 18:00 on day 1 will be re-allocated to a start window of 07:00 – 07:15

Chasing Start Times

There will be a chasing start between 07:00 and 08:00 for the leading finishers on Day 1 in the linear courses, alongside a Leading Teams start for the Long Score and Medium Score. There will not be a chasing start for the Short Score.

Note that there will be designated lanes for chasing starts – please ensure you go to the correct lane.

The start time of the teams in the chasing start will be displayed at the campsite on Saturday evening as soon as possible after 18:30. Remember to check to see if you are in the chasing start. Every year some teams miss the chasing start, as they do not check their Day 1 results. You might have done better than you think!

REMEMBER to check the board on Saturday evening to see if you are in the Chasing Start/Leading Teams start or have been reallocated an earlier start time.


The finish point will be shown on competitor’s maps.  Pairs must finish together. Failure to finish as a team will lead to disqualification.

After you have finished, please grab yourselves a cup of water and one of hot squash, and go straight to download your tag. You will be given a printout showing the controls visited, with points and split times. Please move away from the area THEN check your printout. If anything is wrong or you need to report having to punch manually, proceed to the enquiry point further down the line.

Your tag will be removed and then head through to the catering area for food.   Please keep a hold of your results slip and show this to the guys serving the food as these will entitle you to a hot meal freshly prepared by our chefs!

Kit Checks: Spot checks on equipment will be carried out at the finish.


All courses will close at 16:00 on Day 2; if you arrive back after this time you will be timed out.

Controls will be closed and may be removed before 16:00 at a time dependent upon their distance from the finish. Control closing time will be displayed on the control description sheet. The intention is to bring in distant controls as soon as possible to inform a search for missing teams if this becomes necessary.


Each control site will have the standard orienteering kite with a two letter code, a SportIdent control station and a standby pin punch.  Each team will be issued with an SI-tag. SI-tags are small plastic pegs that have an electronic chip in one end.  The SI-tag is dibbed into the hole in a control station in order for competitors to register that they have visited the control. The control station gives an audible bleep and a visual flash to confirm that the dibbing has been successful.

Some controls will have 2 or 3 stations available to avoid queues – you can punch at any station at a given control point. In the unlikely event that the control station doesn’t register, please record your visit on your map using the manual pin punch in the space provided and report the fact to the marshals and after you pass through the finish.

Many controls will be manned by race officials who will  endeavour to record the time of each team passing through the control. Please assist the control officials by clearly announcing your team number and class prefix i.e.: E,A,B etc. Teams are requested not to use the control points as resting places or for the consuming of refreshments since this distracts control officials and shows approaching teams where the control sites are.


The SI tag will be attached loosely to your wrist at registration using a tamper proof wrist strap. This must remain attached all weekend and be cut off you either when you finish or if you retire but only at the Event Centre. You will be at risk of disqualification if you remove the tag from your wrist. You will quickly get used to carrying the tag on your wrist. Wrists do swell during exercise and providing it has been attached loosely; you will hardly notice that you are wearing it overnight. If you lose, break or take a tag home with you the charge will be £35.00, the use of your own SI-tag is not allowed for safety reasons.


The tag has your team number printed on it and is the only way we can tell who is still out on the course.

Tags MUST be returned to the event centre by 16:30 hours on the Sunday before you leave the competition area: Missing tag = Missing team = Search party.


The presentation of prizes will take place near the refreshment area. There will be 2 prize presentations: B, Combined & Short Score at 1400 hours, Elite, A, Long & Medium Score at 1530 hours.  The Military Competition and the Hutton Trophy will be presented at the same time as the Long Score.  Prizes will consist of vouchers to spend on OMM or Extreme Food product and the value of each team prize is shown below.

MILITARY CLASS – Hutton Trophy

THE OMM has a well established Military Class competing for the Hutton Trophy. Donated by Col Jim Hutton OBE for the highest placed team on the Long Score event.  Both team members must be currently serving or, have served previously in the military for at least 3 years.
In accordance with DIN (2016DIN07-124) – Authority for Army Orienteering
Commanding Officers may deem that the Original Mountain Marathon (OMM) further contributes to the unit’s individual or collective military training outputs; particularly navigation skills; when those planning to participate have suitable experience to safely take part when conducted as individual military training.
About the Hutton Trophy

huttonPresented for the first time in 2010 at the OMM Dartmoor, the Hutton Trophy was presented to OMM by the family of Marine Jamie Hutton who was tragically killed in a training accident in 2008. Jamie and his father, Jim, also known as Col Jim Hutton OBE, Royal Marines, were the highest placed family team in their category in the Brecon Beacons OMM in 2004.  The Trophy is a Commando Dagger in a chunk of Dartmoor granite, which represents everything that the event stands for.  Designed to test teamwork, intelligence, determination and a robust sense of humour the OMM offers a different challenge every year.  



A veteran is defined as a person who is over 45 years of age or more, and a veteran team for the purposes of this handicap is a team in which the combined age of members is 90 years or more. The handicap allowance of a linear class veteran team can be calculated at one minute per hour of running time for every two years of age increment over 90 years, i.e.: 90/91 years is awarded 1 minute per hour of running time 92/93 is given 2 minutes, etc. The score handicap to be 1.5% for each year over the combined age of 90.


A family team will now consist of 2 members who are closely related and from a different generation e.g. father and daughter, grandmother and grandson.

The fifty year history of the OMM event is entwined in the development of the UK outdoor community and industry as a whole. Here’s some things you didn’t know about the OMM:

  • In the early years, compact & lightweight equipment simply wasn’t available. Mountain Marathons pushed the boundaries of racers and kit, OMM innovated to meet this need.   Today’s OMM packs and clothing are less than half the weight of 1968 products and designed and tested for the event competitors needs.
  • The course requires a 420km2 area of wild space.
  • It takes over 100 volunteers to put on the weekend.
  • The impressive list of previous competitors competing regularly includes Joss Naylor & Sir Ranulph Fiennes.  “My last race prior to attempting the Eiger was the Karrimor Mountain Marathon (renamed the Original Mountain Marathon) in October 2006, aged sixty-two years. My team-mate and leader was John Brooke.” – Sir Ranulph Fiennes
  • The event is not for profit and any surplus after costs is donated to charities to improve hill access and outdoor education.
  • The OMM was the first event to have its own custom map after discussions with Elite competitor and HARVEYS Maps owner, Susan Harvey.  To this day the OMM hill team provide ground assessments to improve UK mapping.
  • The planning team are advisors to the governing bodies and national parks. The teams’ decades of experience with ecologically responsible events has helped the BMC develop guidance for access and use of upland areas.
  • In 2013 after impressing the Brecon Beacons National Park with the organisation and ecological responsible approach the planning team helped the park to write their best practice documents for events.
  • In 50 years the event has only been cancelled once… ‘The great storm of 2008″ made headline news.

As the OMM heads to it’s 50th Anniversary the future looks exciting.  An increasingly diverse field and a new OMM LITE event series introducing the next generation and new outdoor enthusiasts to the October event, ensuring the OMM will continue for many years after the 50th. The event is an important part of the UK outdoor history and we want to make sure the event will continue for generations to come. Everyone behind the OMM wants to keep the event fresh and exciting and we’re pleased to see our long standing competitors return each year as well as new competitors coming in from other sports such as Orienteering, Ultra Running & Fell running. Uniquely the OMM is one of the few places you’ll see competitors predominantly compete in one sport against competitors from other sports.

Looking ahead to this October we have a very special weekend planned and it will be one not to miss. We would like to invite anyone who has been involved or competed over the years to join us on the Friday night for an evening celebrating the community that has made the event what it is today. We would also welcome any supporters of competitor to join us and cheer them all back on the Sunday. As is the 50 year tradition the event location will be released in August. See you in October.
