In reply to Duncan Bourne:
It says 100 in "a day" but the way I read it, he appears to have started late and knocked off early to go to the pub. I expect he could have done a couple more routes if he'd been fit enough to keep going for the full 24 hours. Perhaps he'll train and come back fitter for another go. I imagine we could see the record pushed as high as 105 in a full day.
