About the Greater St. Louis Half Marathon
GO! St. Louis uses its spring marathon weekend to bring clubs and individual runners into the same downtown event. The half offers the city-scale experience without the full-marathon commitment.
Course
The road route is designed as a St. Louis city tour, moving between downtown landmarks before returning to the central finish celebration. Urban turns and small elevation changes favor attentive pacing.
Race-day weather
Early April can be cool, windy or rainy along the Mississippi. Conditions may warm quickly after sunrise, so runners should plan for a wider range than the start temperature suggests.
