About the Event

The Guantlet 5K, 10K, and 15K returns to Oakes Quarry Park in Fairborn, Ohio on August 15th, bringing runners a scenic and challenging trail run through limestone cliffs, wooded trails, and stunning quarry views. This annual event offers three distinct distances for all levels of runners: the five-kilometer race for those looking for a quick yet invigorating experience; the ten-kilometer option for an extended adventure on rugged terrain; and the fifteen-kilometer route for serious trail enthusiasts seeking a longer, more demanding challenge.
Set against the backdrop of early autumn in Fairborn, Oakes Quarry Park transforms into a vibrant tapestry of nature's colors. As runners navigate the winding trails that wind around limestone cliffs and through dense woodlands, they'll feel the crisp air on their skin and hear the rustling leaves underfoot. The park’s natural beauty is complemented by the community energy; locals gather to cheer for participants while enjoying the serene surroundings themselves.
The Guantlet 5K, 10K, and 15K have been a staple of Fairborn's running scene since its inception in 2018. Each year, hundreds of runners lace up their shoes to take on the challenging terrain, with many returning year after year for the sense of camaraderie and adventure. Overall winners receive special recognition at each distance, while all participants earn a finisher medal as testament to their accomplishment. The race supports local conservation efforts by raising funds to maintain Oakes Quarry Park’s trails.
The course itself winds through the picturesque terrain of Oakes Quarry Park, featuring rugged limestone cliffs, dense woodlands, and scenic overlooks that offer breathtaking views across the quarry. With its mix of steep inclines and technical sections, this trail run is designed for those who thrive on challenge. Aid stations are strategically placed throughout each route to provide hydration and energy boosts as needed.
On race day, runners can expect a course marked with clear signage directing them through the park's winding trails. The start/finish line will be near the main entrance of Oakes Quarry Park at 1267 E Xenia Dr in Fairborn, Ohio. Participants should prepare for an elevation profile that includes significant climbs and descents; while the route itself is marked with distance markers every mile or half-mile, runners are encouraged to familiarize themselves with the terrain beforehand.
Weather conditions on race day typically feature comfortable temperatures ranging from 17.2°C to 27.5°C, though it may feel slightly warmer due to humidity levels of around 72%. The chance of rain is minimal at just over two millimeters expected throughout the day. Trail surfaces are generally hard and dry, making for firm footing underfoot even on challenging terrain.
