Clinton Lake Ultra

Embark on a challenging yet rewarding trail adventure at the Clinton Lake Ultra on March 28, 2026, in Clinton, IL. Offering both a 30-mile ultra and a 10-mile race, this event invites runners to experience the dynamic terrain of the Clinton Lake State Recreation Area. The course is predominantly single-track, winding through scenic forests, rolling hills, and lush meadows, with only a small section on a road and bridge connecting parts of the loop. Prepare for a significant challenge, as each 10-mile loop features approximately 1500 feet of elevation gain, making it a demanding "roller-coaster" course for Central Illinois, and an excellent training ground for those eyeing more mountainous races.

Runners in the 30-miler will complete three invigorating loops, each supported by two fully stocked aid stations to keep you fueled. This race prides itself on a "no cups" policy, encouraging participants to carry their own hydration bottles or collapsible cups, aligning with a commitment to reducing waste. Beyond the physical test, the Clinton Lake Ultra fosters a strong community spirit. It's a "no chip timing" event, emphasizing the pure running experience and camaraderie over precise individual metrics. Adding to its unique character, the race features a mandatory volunteer requirement, promoting a culture of giving back to the running community or engaging in trail maintenance.

Starting at the North Fork Trailhead Parking lot, participants consistently praise the supportive volunteer staff and the rewarding, albeit tiring, journey through the rugged hills. Typical race day conditions in late March include comfortable highs around 58°F and lows near 36°F, with a modest 15% chance of precipitation, providing ideal weather to kick off your spring racing season. This long-standing event, established in 2007, also contributes its proceeds to various charitable organizations, including those dedicated to trail upkeep.
