Pretty cool. Are track tandems fixies? I got to ride on the velodrome at the Olympic Training Center in Colorado Springs at the end of Ride The Rockies in 1999 (on a single fixie). It was pretty grueling even doing just a few laps. However, I had already ridden 70 miles or so that day. They made the offer to all of the RTR participants and I think I was the only one to take them up on it. I seem to recall that the Olympic velodrome was quite a bit smaller than the one in the video. I assumed they were all the same size. True?
