There' s a randonneur in BC who is quite well known for eating nothing but ice cream on the road... and not only does this guy *routinely* crank out 400 - 800 kms nonstop, but he once took a break in the middle of the Rocky Mountain 1200 (because he was getting ahead of the timing points), left the course, ran a marathon, came back and finished the 1200km route well within the time limit. And the guy is in his fifties. I'm going to figure he knows what he's doing with that Haagen-Dasz...
Dangit. Now I want ice cream. I nearly bought some yesterday but decided on yogurt instead. Regretting that decision!!
