From the Organizer
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, and we want you there to help celebrate as you experience the excitement of running America's longest Main Street in the historic town of Belleville, IL, in the heart of America and just a short drive from downtown St. Louis, MO! Our anniversary celebration will feature fabulous swag, including the first 900 registrants will receive a pair of goodr sunglasses as part of their registration!!! And we encourage you to rise to the challenge of 26 (point 2) miles on the 26th, in '26 to receive even more swag!!! As you make your way down Main Street on race day, you will be greeted by enthusiastic volunteers on every corner, providing incredible support and cheers with the charm of a Midwest town. 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. In addition to bonus anniversary swag, registrants will receive a soon-to-be your favorite everything T-shirt and finisher's medal. Post-race celebrations include Belleville's Bennie's Pizza Pub pizza, a special beer brewed just for you by Belleville's Shoehorn Brewing (for those ages 21 and older), and a DJ for a festive atmosphere. 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.

About This Sport
Endurance Grid is here to help you understand the sport, decide if it's the right fit, and learn how to prepare. For course distances, logistics, and race-day specifics, always defer to the race organizer's event page.
The half marathon is the distance where you find out what you're actually made of. Long enough to demand real preparation. Short enough that it doesn't consume your life to train for it. Most people who run their first half describe it as the race that changed their relationship with what they're capable of. Once you cross this finish line, the bar moves. That's not a warning — that's the point.
Race day energy varies by event size, but the finish line feeling is the same regardless. Big races keep the noise going the whole way. Smaller races give you stretches where it's just you and the miles — and that solitude becomes its own kind of fuel.
The half marathon rewards people who show up for the boring training miles.
How long to train: 10–14 weeks. If you're already running consistently, 10 weeks of structured buildup is enough. If you're building from a casual base, give yourself 14.
Running
From 5K to marathon, running races are the most accessible entry point into endurance sport. There's a distance for every fitness level and a community at every start line.
