BMBO want the rules for our sport to be simple. The aim is to keep rules to the minimum, to achieve good public relations, safety & fairness.

1. Competitors must report to the finish even if they retire. Failure to do so may render entrants liable to search and rescue costs. 
2. Competitors must wear a helmet, carry a whistle and 1st aid kit - minimum of plasters and dressing to stop a severe cut bleeding. 
3. Competitors may use tarred public roads, RUPP's, BOAT's and bridleways plus any forest, estate tracks or white roads specified by the organisers on the event map. Use of footpaths, any other road, trail, 'out of bounds' or leaving the map area will result in disqualification from the event. 
4. Competitors must close all gates, pass or overtake walkers and equestrians slowly and courteously, treat the rural commmunity with due   consideration and aim to cause no damage to the environment. 
5. Team Members must keep in voice contact at all times - including control sites and finish. Penalty 25% loss of overall score. 
6. Individual solo and team competitors must navigate and ride independantly of other competitors. Penalty 25% loss of overall score. 
7. Competitors must offer assistance to any competitors who are injured or in danger. Compensation for time lost can be awarded at the discretion of the event organiser. 
8. Any disputes will be handled by the event referee appointed by the organiser. Any appeals will be adjudicated by the BMBO committee.
9. Pre-riding an event area is not considered to be within the spirit of the event. 
10. For events with control cards competitors should punch controls in the appropriate numbered box. Genuine mistakes must be reported on the finish line as mispunching. Failure to do so may mean that you will not be credited with the points for a control.
11. Event organisers may add their own local rules but may not ignore these rules. 
12. Towing or the use of towing aids is not allowed.
13. The use of GPS or mobile phone to aid navigation is not allowed.
14. Competitors are normally expected to visit controls by riding or pushing their bike.  In very difficult terrain, a competitor may leave their bike while they walk to and from a control.  Even without a bike, competitors must only use the tracks permitted in rule 3.
