Clinton Lake Ultra

Welcome to the 2027 Clinton Trail Running Ultras, where trail enthusiasts converge on the scenic trails around Clinton Lake State Recreation Area for an unforgettable endurance challenge. This year’s race offers two exhilarating distances: a grueling 30-mile ultra and a more accessible yet still challenging 10-mile event.
The course winds through three loops of pristine forest, rolling hills, and serene meadows, each featuring about 1500 feet of elevation gain. The trail is predominantly single-track with brief stretches on road and bridge connecting the loop around Clinton Lake. Runners will encounter two fully stocked aid stations per loop, ensuring they are well-supported throughout their journey.
Registration for race shirts closes at midnight on March 1st; after this date, there’s no guarantee of receiving a commemorative sweatshirt. Early bird registrants can also participate in the 50K MashUp and receive special recognition items upon packet pickup.
Volunteering is mandatory this year, with options to help at other races or engage in trail maintenance work within Central Illinois. Details on how to fulfill your volunteer requirement will be available closer to race day through a form provided by Race Director Mark Kirkland.
The atmosphere at the Clinton Trail Ultras promises camaraderie and support among participants as they tackle this challenging terrain. Post-race festivities include weather-appropriate food, ensuring everyone can celebrate their achievements together.
Join us on March 27, 2027, to kick off your spring racing season with a memorable run through one of Central Illinois’ most scenic trails!
