A weekend trail running, camping and

exploring the Surrey Hills.

The Challenge: 

30+ checkpoints of different values are spread out around the trails and paths near the event centre. Teams have to find as many as they can in their allotted time using the OMM LITE map. The team that collects the most points over Saturday & Sunday are the winners.

The highest summit of the Surrey Hills AONB, Leith Hill, is the highest point in southeast England whilst the ancient Holmwood Common was once owned by King Harold and William the Conqueror.  The area we are using is crossed by a number of well know walking paths including the Greensand Way.


10km – 70km

Course Options

Some focus on running hard and collecting all the checkpoints. Others focus on the social side of things making the most of the Saturday evening and stopping for lunch during the day. It’s up to you how far you go, the most important thing is that you enjoy your weekend.




Route: You decide! The paths and trails to take is up to you.

Distance: You choose! Clear the course or get 1 checkpoint and go for lunch.

Terrain: Trails, Paths, Bridleways.

Skills required: Teamwork, route selection….intelligence.

Campsite: Park close to your tent, bring you BBQ and be comfortable.



Friday and Saturday evening is all about the campsite. Relaxing with friends after a day in the hills. You can park close to your tent and bring everything you need for a comfortable weekend. We have a 50ft marquee with catering and bar on site that everyone is welcome to use.  As well as sports masseurs on hand to ease those aches and pains ready for Sunday.

OMM Lite Competition Rules and Code of Conduct

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 potentially banned from future events.

1. THE GOLDEN RULE: Once registered, competitors must report to the event headquarters and download (and on Sunday return their scoring tag) by 17:00 hours whether they have completed the course or not. If this is not done the team is deemed missing and will be searched for!

2. Long Score, all competitors must be 18 years old on the date of the competition. In the Short Score, all competitors must be 14 years on the day of the competition and the combined age of the team must be at least 35 years.  Any competitor under the age of 16 not competing with their parent/guardian must complete a parental consent form.

3. At least one member of the team must be able to read a map using a compass, without the aid of GPS devices.

4. The event is for teams of two and pairs must maintain contact (communicate by voice) throughout the competition. Both team members must visit the control sites together carrying all their equipment. ie: rucksacks must be in possession of the teams at all times and both team members must dib in the control box.  If one member of the team cannot continue the whole team is retired – the map provides an emergency telephone number. The only exception is in the case of an emergency, when competitors must exercise their own mountain judgment as to the appropriate action to take, including leaving a partner in a warm safe environment to seek help from others.

5.  This is NOT an open access event.  All competitors must keep to public or permissive rights of way (as per event map). Out of Bounds areas and compulsory crossing points are also marked on the event map and must be respected.

6. Teams must carry or wear the equipment and clothing on the official kit list. This is the absolute minimum for safety.  A signed kit list and declaration form must be handed in at registration

7. Well behaved dogs are welcome at the event HQ but must be kept on a lead at all times.  Dogs are NOT allowed to accompany competitors on the course.

8. Competitors must not seek to obtain unfair advantage by searching for courses or inspecting the competition area before the event. Note: Access permission to the competition area is restricted to the weekend of the event only.

9. Use of GPS and mobile phones is not allowed. We encourage you to carry a mobile phone but this should only be used in an emergency and not be used for navigation purposes.  Any team found doing so will be disqualified.

10. 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.

11. Competitors must permit the examination of their equipment by race officials at all times.

12. On completion of the course all competitors must still be in possession of sufficient rations for an emergency.

13. No open fires permitted anywhere on the course or at the Race HQ.

14.  OMM Ltd reserve the right to use any digital media captured at the event for promotional/marketing purposes.

SCORE COURSES (points based competition):

You will be given a map when you register, on it are all the checkpoint locations available during the event. You don’t know which checkpoints are active and how many points they are worth. When you reach the start line you are given a list of the the active checkpoints and their values for that day. The team that collects the most points in the time allowed wins. One benefit of the score course is that you don’t have to stay out for the whole time allowance and can finish when you choose.



Short Score

The Short Score – fixed period competition with time limits of 5 hours on the first day followed by 4 hours on the second where teams accrue as many points as possible. Checkpoints are assigned points values based on their location and teams are free to choose their route to gain the highest score possible. Points are deducted for being outside your allocated time limit. This course is as challenging as you choose to make it and is perfect for first 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.

Long Score

The Long Score – fixed period competition with a time limit of 7 hours on the first day and 5 hours on the second day where teams accrue as many points as possible. Checkpoints are assigned points values based on location with competitors free to choose permitted routes for the highest score. This course tests navigation ability and is as physically as challenging as you choose to make it. Points are deducted for being outside your allocated time limit . Experience and fitness is required. Teams with members under the age of 18 must have competed on the Short Score or similar courses in the past.

Topography Overview




No matter what your level of experience, fitness or mental resolve there is always someone who can teach us something that will help us to improve.

Whether that is advice on kit and packing, race techniques, navigation, nutrition, training programmes or you are brand new to mountain and trail running, Joe and the team at Nav4 have a wealth of experience in these areas, both as competitors and coaches.

Even if you would just like some advice pick up the phone 01768 864909 or drop them an email to see what they can do


Any decisions to reduce the amount of kit you need to carry (e.g. in exceptionally warm weather) will be posted at Registration and on the information board on Saturday morning.

You do not need to bring all your kit to registration for checking, however random kit checks may be carried out at any point during the event.

All competitors are required hand a signed Kit Check List and Declaration to Registration before competing


  • Taped waterproof jacket with hood
  • Taped waterproof trousers
  • Clothing suitable for mountain running and walking
  • Spare warm layer top
  • Hat (this can be a buff) and gloves
  • Footwear suitable for trail and fell use
  • Whistle & Compass
  • Map (as supplied)
  • First aid equipment
  • Pen/pencil and paper capable of being used in wet conditions
  • Survival bag (not a sheet)
  • Emergency rations

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.



Each checkpoint will have the standard orienteering orange and white sign with control station attached to it. Each competitor will be issued with an SI-tag. SI-tags are small plastic pegs which have an electronic chip in one end. Your SI-tag should be dibbed into the hole at each control station in order for competitors to register that they have visited the control; it gives an audible bleep and a visual flash to confirm that the dibbing has been successful.

In the unlikely event that the control station doesn’t register, please record your visit on your map by writing the 3 letters shown on the control box into the space provided and report the fact to the marshals and after you pass through the finish.

After finishing on day 1 you will be directed to the download station where you will dib your tag and be given a print out 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.  Make sure to keep your tag on overnight to use on the second day.   At the end of day 2 you will follow the same procedure and your SI-tag will be removed.


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.


The tag has your team number printed on it and is the only way we can tell who is still out on the course. All tags MUST be returned to the event centre by 17:00 on the Sunday before you leave the competition area: Missing tag = Missing team = Search party.


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 go immediately to download where you will be given your score printout, then make your way to the food area, show your printout and enjoy some well deserved hot food and drink!


The prize ceremony will follow the hot meal and will be held in the marquee at approx. 2pm on Sunday.  Details to follow:

Up to 24 Jun 17.  Changes to names and to the course you have entered can be made by emailing

After 24 Jun 17.   Changes can be made at Registration.  Emergency contact name and number will be required.


For any cancellations received up to  3 May 17, a full refund is made.  After this date we cannot offer a refund as we have already paid for your attendance.  The event is run on a not for profit basis and one of the ways of keeping the costs as low as possible is to agree numbers as far in advance of the event as possible, hence why it becomes more expensive to enter as we get closer to the event.  For these reasons we are also unable to defer entries to future events.



The organisation of the competition is conducted by a small army of unpaid volunteer helpers drawn from a wide variety of clubs and organisations, including the many faithful stalwarts who help out every year and without whose experience it would not be possible to conduct such an event.  These teams of volunteers allow us to keep the entry fees as low as possible to benefit you.

The officials listed are the principal organisers and team leaders:-

Event Director: Stuart Hamilton

Event Coordinator : Emma Gill

Course Planner:  Dave Chapman

Event catering: Matt and Fi, The Old Post Office

Infrastructure & logistics: Simon Peers, North Yorks Scouts
