10K Course
We have new race courses in 2026! We will start and finish in at the T shaped pavilion between the D and E fields. Parking is located in the lot just west of the pavilion and E fields. The 5K and 10K will start and run together for the first couple miles. After getting onto the levee trail, the 5K will turn around and come back to the finish, but the 10K will continue on the trail, under the highway, by the outlet mall, and then turn around and come back.
