All-Out Spring Fever

From the base of Table Mountain and Colorado’s spectacular foothills, All-Out Multicourse presents the 8th annual Spring Fever from Jefferson County’s NAAC Stadium, easily accessible from several nearby highways.

These 1M, 5K, 10K and Half Marathon courses will hug the shores of Arvada’s Blunn Reservoir via the Ralston Creek Trail and will challenge the beginner and veteran athlete alike.

Half Marathon Athletes will depart the east end of the NAAC parking lot then utilize the sidewalk on the south side of W 64th Pkwy to reach the 2nd underpass and the path that runs adjacent to the west side of Virgil Wy. Turning right to go east on Ralston Creek Trail, half athletes will complete a 7 mile out & back dogleg before rejoining the counter clockwise Blunn Reservoir loop. Utilizing the underpass at the reservoir entrance, athletes will make their way back up onto the 64th sidewalk then return they way they came to the finish line. Porta-poos will be available near the 2, 3, 5, 6 & 8 mile marks, and 6 aid stations will offer 8 opportunities for athletes to fuel up every 1 to 1.5 miles.
