Gateway Motorsports Criterium

If you think riding your bike on the streets of St. Louis is dicey, where does a NASCAR Superspeedway rank on the terror factor? Not to worry, because during the Gateway Motorsports Criterium only bicycles are on the track at Gateway Motorsports Park (700 Raceway Boulevard, Madison, Illinois; www.bigshark.com). It's a 1.6-mile, mostly flat course that uses both the NASCAR oval and the roadway portions of the track. Races start at 8 a.m. Sunday, August 19, with the juniors and wrap up with the 5 p.m. Fixed Gear Criterium.
