This is a really well written article about 49 year-old pro cyclist Steve Tilford. It's long, thorough, and enjoyable to both bike nerds and non-bike nerds.
I bet he's a pretty cool guy to ride with. Every time I hear his name, I think of that cyclocross race a year or two ago where he fell into a lake (on a cold day in late fall), climbed out of the lake, then won the race.
And he talks about his demoralizing mistake from the start of this year's elite national cyclocross race when he bobbled his pedal. He still managed to finish 18th out of 75 of the best racers in the country, many of whom were half his age, give or take a few years.
