Off topic is this link I've been sitting on for a while. Not only a MountainRunner, I was also a MountainRider (bartered my 22.9 lb full-suspension cross country mtn bike for massages... a lot of massages) and a RoadRider (and tri-geek). Now the rollers, CompuTrainer, and bikes just rot in the garage begging to be used. Enough of the tears. To share the joy of riding, check out this vid of the NYC Drag Race of Feb 2004 (50mb so it'll take a few to download, but it's good, turn up the sound). If you don't know anything about bikes, some of these guys are on track bikes: no brakes and no freewheel. You pedal and the wheels turn. Stop pedaling and the wheels stop turning.
