Last Saturday I participated in the 2nd 100 Miles of Nowhere Ride, from the one and only Fat Cyclist. (Note - he is the only capital F capital C, I most certainly am a fat cyclist.) The whole thing got kicked off last year when Fatty had the (INSANE) idea to raise some money for LAF by doing a century ride, on his rollers. He took "bets" in the form of donations on whether or not he would finish it (he did). This year he opened it up to other riders (read suckers/nuts). For a small entry fee you got some great loot and the comfort of making a donation to LAF, oh, and the opportunity to hamster-wheel yourself a century.
The day of the "race" was the day before I had to get on a plane for a 5+ hour flight to Hawaii (don't get jealous, I'm working including working on Memorial Day) so I didn't have as much time to set aside as I'd hoped. I also realized that I didn't have a computer on the bike hooked up to the trainer making accuracy a problem. So I opted for the "5 hours of nowhere ride" with the following logic: my average roadspeed (baring wind) is 13 miles/hour; my goal was a metric, which is about 62 miles; at 13 MPH 62 miles should take 4:45; so if I ride 5 hours I can call it a metric and we're good.
In total, I spent about 6.5 hours for the ride, with some stretch breaks and bathroom runs. I ripped through most of the last half of The Black Donnelys (Netflix), with some breaks for Simpsons to mellow things out. It was about what I expected - uncomfortable after a while (I don't have a good seat on the trainer bike), not very exciting, and surprisingly fun.
Oh, and I'll probably do it again next year if it happens.
