The annual Burning River Endurance Run & Relay 2026, produced by Western Reserve Racing, offers 100-mile, 50-mile, and Marathon solo runs as well as 100-mile relay options in Northeast Ohio. The 100 is a qualifier for the Western States 100 and acts as the third leg of the Midwest Grand Slam of Ultra-running. Strambecco rates Burning River as one of the best trail-running events in the Midwest.

The race travels through several of the region’s most scenic areas through the valley carved by the Cuyahoga River, including the Cuyahoga Valley National Park, Summit Metro Parks, and Stow Parks. The 100-mile route features approximately 70 miles of single track and bridle trail, with sections of crushed limestone towpath and road. As you navigate the rolling terrain, you’ll encounter a rich variety of plant and animal life, showcasing Northeast Ohio’s diverse ecosystem. You’ll run alongside streams and rivers along the way, tracing the historic Ohio-Erie Canal Towpath. Take a moment to appreciate the historical markers and catch your breath before ascending the trails through hardwood forests shaped by glaciers and swift-flowing streams. Amidst the leaf-strewn paths, you’ll also enjoy sunny interludes in open meadows and have the opportunity to traverse the rails-to-trails Bike & Hike path towards the 50-mile mark at Silver Springs Park.

The 100M course is Out-Back from Cuyahoga Falls to Silver Springs Park and back (30-hour cutoff – 4:00 am start). The 50M course is point-to-point from Cuyahoga Falls to Silver Springs Park (15-hour cutoff – 5:30 am start). The Back Half 50M is a point-to-point from Silver Springs Park to Cuyahoga Falls (16-hour cutoff – 6:00 pm start). The Marathon course is point-to-point from Oak Hill to Silver Springs Park (14-hour cutoff – 6:30 am start). The 8-Person Relay runs the same Out and Back course as the 100M event (27-hour cutoff – 7:00 am start).

The Midwest Grand Slam of Ultrarunning was established in 2012 and is comprised of completing any four of the midwest’s premier 100-mile trail races: Mohican Trail 100; Kettle Moraine 100; Burning River 100; Hallucination 100; Indiana Trail 100. Runners completing all five races are designated “Super Slammers.”
