Course Description
The Diamond Valley Lake Marathon course is rolling with no major hills. Approximately six miles of the marathon is on smooth asphalt with the rest on compacted dirt access roads with some loose gravel, sand and rocks.
Runners will first run a 2.5 mile out-and-back segment from the Start/Finish area in the East Marina. This will follow a westerly direction from the paved parking lot along the dirt north shore drive road.
Once the course returns to the East Marina, runners will complete 21.2 mile clockwise circumnavigation of Diamond Valley lake on Lake Shore Drive.
