I have just spent a wonderful few hours marshalling at Devon's infamous Wild (and Mild) Night Run. The Wild being a 10 or so mile jaunt across [a very wet and very boggy] Dartmoor, and the Mild just a five or so miler. The runners set off at 6:00 and the first ones back passed me, with half a mile left to go at 6:35, and the rest of the run was downhill. HOW DO THEY DO IT? OK, many were stick-insects with twisted sinews for legs, but even so... it's not natural!
