Registration, Start & Finish are at Jubilee Retreat, Bury Rd, Chingford, E4 7QJ


The race route consists of 10 x 5 mile loops on forest trails and tracks within Epping Forest, woodland operated by the Corporation of London

The loop itself is a fraction over 5 miles bringing the course out at just over 50m. But remember it has 3680ft/1120m of climb and GPS accuracy in the woods is not great! Come ready for roughly 50-51 miles of incredible forest trails.


You are required to cross the timing mat outside the Orion Clubhouse at the end of every lap. Failure to do so will result in a DNF.

Spectating is very much encouraged along the course and straightforward interactions with runners are allowed (cheering, handing a drink or passing/taking non-mandatory kit)


There will be a dedicated team of race medics available throughout the race including a static first aid team at the start/ finish check point and a roving team within the forest. If you suffer an injury or accident that warrants direct medical attention, the medics will be on hand to provide you with exactly that. Contact numbers and full details of what to do in an emergency will be given to you in the pre race information packs and again at race registration. Due to the nature of the course the medics may take some time to reach you, or potentially be out of contact tending to other runners. In those instances you should contact the emergency services on 999 AS WELL AS the race medics.

Some useful independent medical advice here


99% of the course is on trail, therefore trail shoes are advised. There are sections of trail which can become very muddy in wet conditions. The course takes a number of ascents and descents, many of which will become hard going in wet conditions, particularly as the race progresses. These sections must be negotiated carefully in both the dry and the wet.
