Burning River 100, live.

100 miles through Cuyahoga Valley and Summit Metro Parks

The 21st Burning River Endurance Run and Relay starts in Cuyahoga Falls, Ohio, on Saturday 31 July 2027 and finishes on Sunday 1 August.

Burning River is a summer trail ultra in Northeast Ohio, organised by Western Reserve Racing. The 2027 edition marks its 21st anniversary and runs on 31 July and 1 August, through some of the most scenic ground in the region, including Cuyahoga Valley National Park and the Summit Metro Parks.

The 100 mile runs out and back from Cuyahoga Falls to Silver Springs Park and back, with about 8,000 feet of climbing. The main start is at 4:00 am with a 30 hour cutoff, and an early start at 2:00 am gives 32 hours. The 50 mile goes point to point from Cuyahoga Falls to Silver Springs Park at 5:30 am with 15 hours, and the Back Half 50 Mile runs the other way as a night race from 4:00 pm with 18 hours. The marathon goes from Oak Hill to Silver Springs Park, starting at 6:30 or 8:00 am.

For teams there is a 100 mile relay for eight people on the same course as the solo 100, starting at 7:00 am with a 27 hour cutoff. The 100 mile is the third leg of the Midwest Grand Slam of ultrarunning and every finisher qualifies for the Western States lottery.

Pacers may join 100 mile participants from mile 50, or at any point for those aged 60 and over. Course maps change up to the day before the race, so supporters should check the latest version before heading to the aid stations.

On Livebib you can follow a participant who chooses to share their own live position from the phone they carry. This is not the organiser's timing, and the official results come from Western Reserve Racing.
