SMALL PRINT RULES, REGULATIONS AND ADVICE
All racers must abide by the countryside code whilst off road and the highway code whilst on the road sections.
All litter must be kept & disposed of once back at the events centre. Anyone spotted or caught dropping litter will be immediately disqualified from this event and all future sporting events. The countryside is beautiful & we need to keep it that way.
Remember we are sharing footpaths with other countryside users like dog walkers, horse riders and mountain bikers. Please offer common courtesy & do not barge your way past people just to get that extra millisecond in your event result. Behaviour like this could jeopardise future events and will result in disqualification if you are spotted doing so.
On route there are marshals/teams strategically placed for your enjoyment & safety. If you find you are struggling, or know of another competitor who is, please inform the closest marshal so they can communicate this to the Event Director back at HQ.
In the event that you have to withdraw from the event after registering for any reason whatsoever, you must inform the event official at the finish line. We have to account for all runners who start the event and therefore if you do not inform us of your withdrawal the emergency services may have to be involved.
On the back of your race number you will need to complete all the details including any medical conditions you suffer from. This is for your protection and your benefit so please complete. We will be inspecting race numbers and those that have not completed the details will not be allowed to start.
Due to the fact that part of the event is on roads open to traffic personal music devices are not acceptable. This is for your’s and other’s safety so anyone found breaching this rule will be disqualified and fed to the wolves.
