About the race
All-Out Multicourse presents the 15th Annual Spring Fever in Golden, Colorado, set near Table Mountain and the Colorado foothills. The event uses local paths and trails around Arvada's Blunn Reservoir and the Ralston Creek Trail, and is accessible from nearby highways. It includes in-person and virtual race options.
Distances:
- Half Marathon 13.1 miles
- 10K
- 5K
The in-person courses start at the NAAC parking lot. The half marathon follows W 64th Pkwy and the path alongside Virgil Way, includes a 7-mile out-and-back on the Ralston Creek Trail, and finishes after a counter-clockwise loop around Blunn Reservoir. Eight aid stations and three toilets are located along the half marathon route.
The 10K departs from the NAAC parking lot, runs east along the south sidewalk of W 64th Pkwy, then north beside Virgil Way before completing the counter-clockwise loop around Blunn Reservoir. There are three aid stations and one toilet on the 10K course.
The 5K leaves the NAAC parking lot, follows the sidewalk to the first underpass and Ralston Creek Trail, runs northwest with the reservoir on the right, turns around at 1.55 miles, and returns on an out-and-back course with two fueling opportunities.
Virtual participants receive event swag and a finishers medal shipped the week after the event, and remain eligible for series finisher awards, alumni brag tags, and modified placement and distance credit toward the Run Amok Championship. The event benefits the People and Pollinators Action Network and features the event mascot Buzzby. Visit the organization's website for the most recent information.
