About the Boise River Marathon
The course follows the Boise River Greenbelt, staying close to the water for most of the route. The river moves through a rocky canyon section before the path opens into the city, so the surroundings shift as you run. The surface is road, the grade is gentle throughout, and the course is designed to run short rather than long, which is why a number of runners post personal bests here.
Packet pickup runs at a local running store the days before the race, with options at the start and finish area as well, including an early morning window on race day. Parking at the start and finish area is free. Marathoners have a gear check near the far end of the course, staffed by volunteers who hold bags while you run back toward the finish.

The Boise River Marathon has been held every year since at least 2022. That is as far back as RunSignup's records for this race go, so it may well be older.
How we calculate these stats: RunSesh calculates these figures from the most recent published results of past editions, sourced from RunSignup. We show aggregates only: field size, winning and median times, and the cutoff. We never publish individual finisher tables. Last updated Jul 27, 2026.
