Event Headquarters









A weekend mountain biking, camping and

exploring the Brecon Beacons.

The Challenge: 

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


5km - 70 km
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 next 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 next 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 Bike 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. Riders (at least one member if in a team) must be able to read a map using a compass, without the aid of GPS devices.

4. The event is for both solo riders and teams of two.  If in a team they must maintain contact (communicate by voice) throughout the competition. Both team members must visit the control sites together and  if one member of the team cannot continue the whole team is retired (the map provides an emergency telephone number).  In the event of accident or illness use all available aids and seek assistance. You should use your mobile phone if you are carrying one, to call for assistance. If you are riding as a team stay with your partner whenever possible, the only exception is in the case of an emergency when you have no mobile phone and you judge the appropriate action to take would be to leave 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. Competitors 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.  Helmets must be worn at all times when riding.

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.



We have a great HQ for the 1st Brecon Beacons OMM Bike event.  We’ll be based at the village hall in Cwmdu in the middle of the competition area where there will be a big heated marquee with plenty of seating, catering and bar, sports massage, toilets, water.

Cwmdu Village Hall


The camping field is right next door and you can park next to your tent.  You can also bring your campervan or caravan just be aware there is no hard standing or electric hook ups.

Camping for competitors over the weekend is included in your entry fee.   You are more than welcome to bring along family or friends, all we ask is for a small contribution of £5 per person for the whole weekend.  Non-competitor camping can be added to your entry when you register or at any time after that by logging into your account.  Pre-booking really helps us out and ensures we have plenty of camping space for competitors and guests.

If you’d like to sleep in a little more luxury then you are welcome to stay in one of the many B&Bs or hotels in the area.  Lots more information on the beautiful and wild Brecon Beacons here.


By Car.  A few miles north west of Crickhowell on the A479.  Less than 50mins from the M4 or M50.   Why not not do your bit for global warming and reduce the cost of the trip by car sharing? Just post on the OMM Forum that you are offering or looking for space in a car…

By Train.  The nearest Station is Abergavenny approx 10 miles from the Event Centre.


SCORE COURSES (points based competition):

Competitor will be given a map when they register, on it are all the checkpoint locations available during the event. They don’t know which checkpoints are active and how many points they are worth. When they reach the start line competitors are given a list of the the active checkpoints and their values for that day. The competitor/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

Short Score – 5 hour day 1, 4 hour day 2 The Short Score – fixed period competition with time limits of 5 hours on the first day followed by 4 hours on the second where competitors 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 at a rate of 2 points per minute or part thereof. 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

Long Score – 7 hour day 1, 5 hour day 2 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 competitors/teams accrue as many points as possible. Checkpoints are assigned points values based on location with competitors free to choose 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 at a rate of 2 points per minute or part thereof.  Riding 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

The Event centre sits more or less in the middle of the competition area, in a long valley with numerous farmsteads, and a watercourse, crossable at a number of places. The area to the west is compact and although hilly, it is slightly lower than the eastern area. This eastern area is quite extensive, with some big climbs, and can attract some robust weather. There will no doubt be some ‘high pointers’ out there, but to over-commit will attract heavy penalties, although good planning will pay dividends. The western area has a relatively close network of lanes, bridleways and paths, but the land to the east is more remote. Take care, as the re-introduced wolf population is growing in confidence. Stick to the permissive paths, or you’ll be disqualified. Or eaten.



  • Helmet (must be worn at all times when riding)
  • Taped waterproof jacket
  • Taped waterproof trousers
  • Clothing suitable for mountain biking
  • Warm layer top
  • 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
  • Water carrying ability
  • First Aid Kit
  • Bike repair kit

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, so Jeans, T Shirts Sweatshirts etc. should not be worn!

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 to sign a Kit Check and Declaration Form and hand to registration before competing



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 5pm 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.  If you are in a team you must finish together, failure to do so 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…

What’s the minimum age for taking part?

You need to be 14 years old to enter and the combined age of the team must be at least 35 years. Any competitor under the age of 16 not competing with there parent or guardian must have parental consent.

Can I enter the OMM Bike on my own?

Yes, you can enter the Bike course as a solo but you must be 18 or over.  If you’d like to enter a team of three then email [email protected].

Do I need to carry a tent and sleeping bag like the October OMM?

Competitors will return to the overnight campsite after Day 1 so there is no requirement to carry overnight kit.

What maps will I be using?

1:40,000 either Harveys or OS maps.

If you have a question that hasn’t been answered in the Event Details pages please do email [email protected]



Up to 14 Apr 17.  Changes to names and to the course you have entered can be made by logging into your OMM account.

After 14 Apr 17.   Changes can be made at Registration.  The competitor must present himself/herself at registration in order to complete the necessary paperwork. Emergency contact name and number will be required.


For any cancellations received up to  2 Mar 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.
