Embark on a challenging trail adventure at the Clinton Lake Ultra on March 28, 2026, in Dewitt, IL. This event offers both a 30-mile ultra and a 10-mile race, inviting runners to kick off their spring season on a dynamic course. Typical race day conditions in late March include comfortable highs around 57°F and lows near 35°F, with a modest 13% chance of precipitation.

The course, starting at the North Fork Trailhead Parking lot, comprises mostly single-track trails winding through the scenic forests, hills, and meadows of the Clinton Lake State Recreation Area. While predominantly trail, a short section of road and a bridge connect parts of the loop around the lake. Runners in the 30-miler will complete three 10-mile loops, each featuring approximately 1500 feet of elevation gain, a significant challenge for Central Illinois. This "roller-coaster" course is renowned for its great views and has even served as a training ground for those preparing for mountainous races. Aid stations are fully stocked and located twice per loop, though runners are encouraged to carry their own hydration bottles or collapsible cups as part of the race's "no cups" policy to reduce waste.

Beyond the physical test, the Clinton Lake Ultra is a "no chip timing" event that fosters a strong community spirit, focusing on the running experience rather than precise individual timing. It's also recognized for its unique mandatory volunteer requirement, promoting a culture of giving back to the running community or engaging in trail maintenance. This long-standing event, which first launched in 2007, donates proceeds to various charitable organizations, including those supporting trail upkeep. Participants consistently praise the supportive volunteer staff and the rewarding, albeit tiring, experience of navigating its rugged hills.
