The Market Mile is a community-based, one-mile walk/run that invites you to give back and have fun doing it by joining us at our great after-party in Union Station!

Beyond the promise of sunny summer weather, a one-mile course straight down Market Street, the “take it at your own pace” vibes and a buzzing after-party at Union Station, the Market Mile is different because it’s powering up the nonprofits who work tirelessly on the future of our city.

The Market Mile serves St. Louis through core areas of need: accessible green spaces, safe housing, public safety, and youth programs. We’ve carefully selected Market Mile Race Beneficiaries that you may choose to support when you register.

We raised over $16,000 for nonprofits in 2024 and 2025!
