velodromes

I'm told a standard velodrome track is 330 m around. There's an indoor track in Los Angeles that's only 250 m, and instead of having 27 degree banking, it has 45 degrees.

I don't know anyone who has ridden on the indoor track, but I hear that while the velodrome in Balboa Park in San Diego is patched and bumpy, it's still pretty entertaining to ride around on.
