The DR40 is the final and longest race of the series. Run over less technical terrain than the first two races in the series, but with over 3,000ft of ascent, this is still a challenging event. Covering a markedly longer distance – requiring strategy, consistency and stamina – the course features good hard-packed trail (Roman Road) and less technical descending, but one steady climb runs to almost 12km!

Starting and finishing at the wonderful Semer Water, the route travels over Stake Moss to Cray. Following the River Wharf up the picturesque Langstrothdale, runners then climb to the Pennine Way taking in amazing views of Ingleborough. The route returns to Semer Water via Cam High Road and Wether Fell.
