Just qualifying for the Olympics is pretty amazing! Congrats to your riders. It was really great to see riders from countries that aren't traditionally big in cycling.
For anyone who hasn't been to a velodrome and seen track races in person, you might think "enh, it's just some folks in tights riding bikes in a circle." I guess pursuit races wouldn't be that exciting, but any event where there is a bunch of riders out on the track together bumping shoulders at high speed is wildly gripping to watch in person! "Miss and out" races are pretty cool - everyone starts in a big pack, and each lap, the last person over the line gets eliminated until someone wins - so every lap has a crazy battle to not be last.
Track cycling used to be a huge thing in North America with lots of betting going on. It still is to some degree in Japan where they have Keirin racing - everyone starts at once as a motocycle rides by - so everyone battles to get in position right behind the motorcycle to get the best drafting. Lap after lap the motorcycle gradually speeds up until it pulls off the track, and everyone sprints to the finish. If you go a good draft off the motorcycle, you should be less tired than everyone else, but in a bike sprint there are no guarantees.
If you live near a velodrome that has race nights ( http://en.wikipedia.org/wiki/List_of...tes_of_America ) go see some races before the end of the summer. Watching a bunch of riders cutting each other off on the banked turn at 35 or 40 mph is total edge-of-your-seat action.
