The course will not be marked by us and navigation will be with the Maps and permanent signs, you will be required to navigate using the 1:25,000 map sheets provided.
The route is well waymarked and signposted but some places are not marked well and you must expect to be using the Maps provided and not rely on the signs.
There will be three checkpoints along the way with runners carrying all kit needed for the duration of the race. Drop bags will be available only at half way - and then subsequently ferried to the finish.

We know rules can be boring but they are here for your safety, and our permit to run the race depends on us running the race within the rules.
The race is run under UK Athletics rules which can be viewed here.
Below are our own race rules in addition to the UKA rules:
This is considered a non-stop race, any runner stopping for more than 2 hours at a checkpoint will be considered retired. This is to stop the event becoming a 2 day event and runners sleeping overnight.
No MP3 players etc. to be worn during the race for safety reasons. If you wear one and can not hear marshals or traffic, this is your responsibility. There are many other users on the footpaths such as cyclists walkers and other runners. Please ensure you can hear them and allow them to pass.
Please display your number on your front at all time (this is a UKA rule as well).
Please obey all instructions by marshals and checkpoint staff as they only have your safety in mind.
Please leave no litter on the route and hand rubbish in to checkpoints as our permit may be at risk if litter is found after the race.
If you drop out for any reason, you must tell a marshal or phone the race director as we don't want to be looking for you at the end of the race.
If you break any UKA or race rules then any decision by the race director is final.
