Okay I know this is an MTB forum and I may have a few berating me!!! But has anyone done the 3 peaks. ... walking! Some friends are doing it on 13th June and I've been invited along. I quite fancy it although realistically how hard is it? I've done some reasonable amount of walking before, I can handle long days without sleep (working shifts as old bill that's the norm). Someone suggested that you have to be "marathon" fitness, I'm not so sure though.
There are designated drivers arranged, and I presume some of the walking ends up being in teh dark so you need PEtzels or similar? What food do you eat in between?
any advice or experiences? Oh and I haven't said yes or no yet .. what do you reckon!!??
