Well, afraid I just recorded my third DNF in the UTMB. I called it a day after about 70 miles, further than I've got before but still no cigar. We're spending the next week walking and enjoying the Chamonix valley, then I'm going for a week's climbing at Ailefroide near Briancon. I'll post the story of my race when I get back.
All the other guys here from the WHW family finished the event brilliantly, congratulations to all!
