The Experience
The Dam Site Run, established in 2020, has quickly become a highlight for Central Illinois runners. Initially created as a rare racing opportunity, its November date proved serendipitous, showcasing the region's vibrant fall colors.
Runners can expect a certified, flat course, ideal for setting personal bests. The race emphasizes environmental consciousness, aiming for a no single-use plastics event with paper cups available at aid stations. This commitment, along with unique swag and a finisher medal, underscores the organizers' goal of providing excellent value.
Race-provided description
The #1 Half Marathon in Central Illinois is taking place on 11/1!
ABOUT THE DAM SITE RUN... The Dam Site Run was created in 2020. It started as simply a rare opportunity to race that year when nearly every other race was cancelled. Turns out, the date meant perfect fall colors as the leaves started to fall in Central Illinois, creating the perfect backdrop for a fall race.
THE TRADITION CONTINUES IN 2026.... You can expect the another high quality race with many of the same features you've come to know and love... Certified course... Unique post race swag... Chip timed, with split times... Awards...Finisher medal... And beautiful fall colors. Our goal is to give you your money's worth.
NO SINGLE USE PLASTICS ... We are challenging ourselves to put on an event with no single use plastics. No plastic water bottles, not even bottles of sports drinks. If we can put on an event and leave a more positive impact on our environment, we should, right? (There will be paper cups available at water stops.)
