Route Map
Chiltern Hills Backyard Ultra Loop
A gentle start until a climb up ‘the wall’, an unforgiving climb up to the top of the ridge. From here, you stay relatively high re-joining the ‘tank track’ through the woods. The second half of the route is relatively flat after the refuge point, opens up under big skies before a final effort to get to the finish.
The elevation gain is 152m, please see below graphic which had one big climb in the first km then flattens out.
Routes are subject to change, a final route will be sent out in the race information pack and can be adjusted on the day for safety or operational reasons.
