Did a taster session with 2 mates at the Newport Velodrome, I don’t even own a road bike but am now looking at second hand fixies. Be careful the dark side is strong there.

(Actually it was amazing going round at the top of those bends, bl**dy knackered after 1h, full credit to Hoy, Trott and all doing that all day long. If you get a chance try it!)
