Going Round and Round

Velodrome racing started in the 1800’s. Madison Square Garden was actually originally built as a track racing venue. Track racing has varied in popularity over the years but is here to stay in Boulder, CO.

Paul Mack submitted this photo from 1901-02 (he didn't take it).

If you build it they will come (video)

And they do come: every Thursday from 5:00-6:00pm the BMCT practices as a team on the Velodrome at Boulder Indoor Cycling.

Quick Facts:
  • Construction: Wood
  • Overall Length: 142 meters
  • Maximum Banking (corners): 45 degrees
  • Minimum Banking (straights): 16 degrees
  • Current Lap Record: 8.001 seconds (Colby Pierce)
Wikipedia offers this technical explanation of riding a Velodrome:
  • Banking in the turns, called superelevation, allows riders to keep their bikes relatively perpendicular to the surface while riding at speed. When traveling through the turns at racing speed, which may exceed 60 kmh (about 37 mph), the banking attempts to match the natural lean of a bicycle moving through that curve. Therefore, the centripetal acceleration of the combined inertia of bicycle and rider moving in the curved path balances the tangential acceleration pulling them outwards. There is no centrifugal force 'trying' to tilt the bicycle outward, a net normal force acting on the tires through the riding surface.
Or you could just explain it as FUN.
