Prepare for an unforgettable challenge at the High Lea 6/12/24 hour race, hosted on May 16, 2026, within the scenic Richfield Heritage Preserve in Richfield, Ohio. This enduring event offers a spectrum of distances to test your limits, including 100-mile, 24-hour, 12-hour (with both day and night options), and 6-hour races. The course unfolds over a roughly 3-mile loop featuring approximately 225-237 feet of elevation gain per circuit, characterized by its mostly shaded, unpaved gravel camp roads and winding trails. Runners will navigate through the historic grounds of an old girl scout camp, past serene lakes, and alongside picturesque waterfalls, with reviewers often highlighting its beauty and undulating terrain, including a notable climb near the loop's end.

The High Lea event, organized by Fast Girls Running Company, maintains an "old school ultramarathon" vibe with a supportive atmosphere, thanks in part to its volunteers, many of whom are accomplished ultrarunners themselves. A full-service aid station, conveniently located at the summer barn start/finish area, provides essential sustenance, including standard grab-and-go options like chips, pretzels, candy, gels, soda, sports drinks, and water, alongside hot food such as ramen, broth, and coffee during the overnight hours. Primitive tent camping is available at the summer barn for participants, enhancing the race's community feel. Pacers are permitted for 24-hour runners after 6:00 PM and for 100-mile participants after 50 miles, offering crucial support through the longer durations.

Typical race day conditions in mid-May present comfortable highs around 72°F and lows around 53°F, with a modest 17% chance of precipitation, creating generally favorable running weather. Beyond the personal challenge, participating in the High Lea race contributes directly to the preservation of its stunning venue, as a portion of the proceeds is dedicated to capital improvements at the Richfield Heritage Preserve. Finishers of the 100-mile race earn coveted belt buckles, while those completing other distances receive medals, with all participants taking home a commemorative race T-shirt. The race is chip-timed, featuring a lap-o-meter and live tracking to keep runners and spectators informed.
