The Hour Record and Marginal Gains, Part 1

The Hour Record is unlike any other race in cycling. Almost unimaginably difficult to do, but elegantly simple in concept: Ride your bike, as hard as you can, for an hour. When you look underneath this simplicity, however, the subtlety, beauty, cruelty, and sophistication of this race become totally gripping. And then you find out there's way, WAY too much to talk about in just one hour. So this is just part 1 of a three-episode series about the Hour Record, covering the origins of the race, early history...and doping.
