Race Info
Now in its 8th year, this event is produced by life-long runners who know the beauty of running, walking, and hiking through scenic and challenging terrain. Run or walk through the stunning Kaibab National Forest, nestled on the Coconino Plateau just a hop, skip, and jump away from the awe-inspiring Grand Canyon South Rim.
Local Partners:
We support Run Local. The Grand Canyon Trail Marathon is a joint partnership between the Town of Tusayan and Run Tucson, the premier local running company in Arizona.
Special thanks to the Tusayan Fire District, the IMAX Visitor Center, and the Kaibab National Forest.
Bring the Kids! Children and strollers are allowed in the 5k
Trail Marathon and Half-Marathon Terrain: half mile start on sidewalk, then 11.5 miles of challenging forest jeep roads, including rugged rocky sections, soft dirt, and hard-packed dirt forest roads, with a rolling final mile on the paved Arizona Trail path. According to the National Park Service, the forest is characterized by ponderosa pine, with Gambel oak, New Mexico locust, mountain mahogany, elderberry, creeping mahonia, and fescue.
5k Terrain: mostly paved Arizona Trail, with about one mile on hard-pack dirt forest road
Difficulty: the marathon and half-marathon course is challenging for many, with hills and rugged terrain. Top runners finish about 10 minutes slower than road races in the half-marathon.
Weather: most likely in the 30's and 40's early morning, with daytime highs hitting 60's - 70's . . . but you never know what late October will bring at 7,000 feet.
Chair Athletes: The 5k would be challenging for chair athletes, while the marathon and half-marathon is on a rugged course not suitable for chair athletes.
Pets Allowed: We love pets but they cannot be with participants on the course during the event.

From Endurance Grid
Endurance Grid is here to help you understand the sport, decide if it's the right fit, and learn how to prepare. For course distances, logistics, and race-day specifics, always defer to the race organizer's event page.
The half marathon is the distance where you find out what you're actually made of. Long enough to demand real preparation. Short enough that it doesn't consume your life to train for it. Most people who run their first half describe it as the race that changed their relationship with what they're capable of. Once you cross this finish line, the bar moves. That's not a warning — that's the point.
Race day energy varies by event size, but the finish line feeling is the same regardless. Big races keep the noise going the whole way. Smaller races give you stretches where it's just you and the miles — and that solitude becomes its own kind of fuel.
The half marathon rewards people who show up for the boring training miles.
How long to train: 10–14 weeks. If you're already running consistently, 10 weeks of structured buildup is enough. If you're building from a casual base, give yourself 14.
From 5K to marathon, running races are the most accessible entry point into endurance sport. There's a distance for every fitness level and a community at every start line.
