2026 Belleville Main Street Marathon and Half Marathon

Get ready to make history with us on Saturday, September 26, 2026, as we commemorate the 10th Anniversary of the Belleville Main Street Marathon and our Half Marathon being designated as the Road Runners Club of America Illinois State Championship Event!!! This year promises to be our biggest and most exciting event yet!

Both the full and half marathon courses are ideal for runners of all experience levels and include Main Street and other city roads. The full marathon is a USTAF-certified Boston Marathon qualifier that also includes about 10 miles on a paved trail.

The Belleville Main Street Marathon and Half Marathon is a non-profit event, with proceeds reinvested back into our community (community food pantry, Belleville Parks and Recreation Department, and a college scholarship fund for Belleville high school students), with $20,000 being donated from 2025 race proceeds. We are a grass-roots event organized by dedicated volunteers from the Belleville Running Club and Toolen’s Running Start.
