On training
I don’t, as a general rule, train. I ride lots, because it’s a pleasant way to spend time and think about hard problems. But, insomuch as “ride lots” (™ Eddy Merckx) counts as training, I don’t think that riding 40 miles last week (35 of which were done on Friday) would count as particularly good training for running a R400 on Saturday.
I will try to get more sleep this week. If I’m rested, going out on the bicycle seems like a better idea.
