Take on 75km (47 miles) with a 24 hour target and 2,235m of ascent, the Silver Challenge starts at 9pm on Friday 17th evening at 9pm. Not to be underestimated, this route follows the easiest and flattest routes between aid stations, but still covers a huge mileage. Your Silver Challenge begins with a trek east up onto the Dark Peak moors. You will cross Stanage Edge, site of Robin Hood’s cave, and Foulstone Moor to reach Back Tor. Next it's a descent to Ladybower Valley and an easy flat section around Ladybower reservoirs where the Dambusters trained for their bombing missions in WWII. The daytime section of your challenge covers a swathe of the White Peak from Baslow back to Hathersage in one large single loop.
