Routes

21.1km Route

A fast start blasting across Bradenham Village before a lung-busting climb up onto Naphill Common. A lovely section of open woodland follows before a fast and firm trail back into the village. The routes then re-join the 10km route with a final couple of hills to finish before dropping back down to the finish line.

10km Route

A very pretty and scenic route around the Bradenham Estate. With 4 climbs and a sweeping final 3km which is all downhill. This is set to be a corker with stunning views, tranquil trails through beech woodland and along massive field margins. There is one aid station approximately at 4.9km in.

5km Route

The 5km route winds up the hill before a steep plunge into quiet woodlands. A final climb awaits before traversing therough the top of the woods and a final 1.5km descent down a track to the finish.

Routes are subject to change and might run a little short or long. We reserve the right to alter routes for safety.
