I am attempting to complete a 54 mile hill walk in the Brecon Beacons in just 24 hours. As Tom completes loads of crazy endurance challenges I thought I should probably get off the supporting sidelines and give one a go with him. 

I have put lots of training into this and am starting to appreciate how much of a challenge it is going to be!!

I am raising money for Marie Curie Cancer Care and my aim is to raise £400. What's even better, anything I raise for Marie Curie Cancer Care will be matched by Network Rail and donated to CLIC Sergeant, Network Rail's chosen charity.
