I'm putting my wonky knees & chunky thighs to the test and walking 100km (62miles) across the South Downs in less than 30 hours...somehow! Part of a strapping team of novice walkers, we've taken the Oxfam Trailwalker training plan, heavily adapted it based on our expert knowledge and it's now a case of mind over matter to get this thing done. We're taking on the challenge for a great cause - any donation gratefully received!
