The rider was Tom Milton inventor/owner of Selle An-Atomica saddles. I didn't know him too well (just the normal chitchat on rides) although I just rode the last 35 miles behind him last weekend on the Davis 400k. He had already racked up over 2000k in just brevets this year. He was happier than ever to be out cycling past midnight and pulled our group in pretty much the whole way.
