Road racing and mountain biking relate easily to the average rider's view of cycling. Track cycling does not. In track cycling, the riders go nowhere, just around and around an oval track banked at 42 degrees. The track's name - the velodrome - sounds space-age, and the helmets, suits and bikes bearing no resemblance to a common two-wheeler more closely resemble something out of Star Wars.
