Now here is a word you might come across now and then, though it's been a while for me. A Velodrome is a building for indoor bicycle races. As to why it's not called a cyclodrome, I'll have to get back to you on that. Apparently there are plenty of them, and they have steeply banked tracks like the one at the left. Sorry to be a wimp, but that would scare the bejeezus out of me.
