Hi - how did you get on? I waddled in under just under 21 hours. Managed to trip over a tree root - worst injury being minor discolation of top joint of little finger - doh - only Bear could do more damage to hands rather feet on an ultra !
Will be be there waddling off at the 8.40 start. 2 litres def. OTT. Plenty of snacks on the way so you do not need to carry too much extra fuel. Route is fairly straightforward and you'll be given a fairly detailed map at registration. Will wear normal running shoes 2 sizes larger than normal with Scholl footpads under forefoot, a pair of liners and walking socks. The path is quite hard and stoney in parts and as it's flat there is a greater risk of blisters as the pressure is always on the same area. Just hope there is not a heavy mist - on one event (not this one) managed to walk right by a check point as it was completely obscured.
