St. Louis

St. Louis running is defined by the Mississippi River and the flat terrain on both banks—the Gateway Arch grounds and riverfront parks offer straightforward mile repeats, while the Chain of Rocks Bridge Duathlon uses the historic northbound crossing. Cyclists dominate the region with strong local racing: the Bommarito Audi West County Gateway Cup and St. Ann Grand Prix are the anchor events, and routes range from the STL Bike Infrastructure Tour's urban network through downtown to the Pedal the Cause century ride that stretches into the rolling Missouri countryside.
