The Back Before Dark 10k challenge starts at 6:03pm on Saturday 23 September 2017 for those running. Runners have just one hour to ensure they’re Back Before Dark. For those looking for a better chance of completing the route, walkers taking part in the challenge can depart much earlier at 4.03pm.

The Trek: The 10km Back Before Dark run leaves Hathersage along the River Derwent and heads west over grassy fields and wide paths. Climbing starts around the 2km mark as you’ll follow Dunge Brook up to the edge of Offerton Moor and wide undulating tracks to pretty Shatton.

Grab some water from the drinks station and the home leg of course leads through flat fields and riverside paths. River crossings provide short leg-burning step climbs for minutes at a time, and the final straight is flat and grassy back towards Hathersage. The total climb is 270m.

Sunset on Saturday 23rd September 2017 is at 7.03pm.
