Heavens Gate Marathon and Half Marathon - May 1 - 2, 2026
Welcome to the Seven Devils of Idaho! In 2026, we are going bigger than ever! 53K (33mi), 26K (16.5mi) and a special Friday afternoon Vertical 3K Race.
53K Race
We are building on our traditional footprint of Cannonball Mountain and expanding the terrain out to an amazing ultra with around 13,000 feet of climbing over its wild and scenic 33 miles. Climbs of 5000'+, 3500'+ and 2000'+ anchor this monster with lots of rolling canyon bottom terrain. There will be a mandatory kit of gear and nutrition, two manned aid stations and some water stations along the way. Right up there with the most challenging races of this distance on Earth. 7AM Saturday start time.
26K Race
The classic loop. Up Blue Gulch and over the top of Cannonball Mountain, down to McRea Cabin and back through the canyon to finish. 6000+' climbing for 16.5 miles. One manned aid station and a few water stations. 8AM Saturday start time.
2-3K Vertical Race (FRIDAY 5PM)
FREE for entrants of the 53 and 26K, possibly a small entry fee for others, we will announce this shortly depending on the US Forest Permit approvals. This is an UPHILL ONLY RACE (1-2 miles with 2500 feet climb) to the summit of Challenger Peak. This is the peak immediately above the Hatchery and Trailhead. We have named it Challenger Peak to honor the sacrifices of the Challenger Shuttle Astronauts on this 40th year since the tragedy. We will start at the Hatchery and climb to the Peak and the race ends there. We will walk down together and have some fun up top and along the way down. A perfect excuse to get to Riggins early and make the most of your weekend.
