California > Grape Stomp Half Marathon, 10K & 5K
Livermore, CA  •  Sunday, October 20, 2013  •  Course Map


More than 1,100 runners crossed the finish line in all three events combined at the 2011 running of the Grape Stomp Half Marathon, 10K and 5K races, which take runners along the winding creekside trail known as the Arroyo Mocho Trail here between Livermore and nearby Pleasanton, on a course that features very gradual hills for the most part for runners in the 13.1-mile race.

Much of this USATF-certified course is fast and flat, and features beautiful views of tree-lined country roads here in the Northern California wine country, as well as a wine tasting for runners, friends and spectators at the finish line festivities. The race also is part of the California Half & Full Marathon Series, which includes 21 races that start with the Davis Stampede race in February and finish with the Walnut Creek Half Marathon in December.

Runners in the Grape Stomp Half will once again follow an out-and-back course that starts and finishes in Livermore's Robertson Park, and organizers note the race will go on rain or shine. From the park, runners head out first on the trails that lead out of Robertson and then onto the Arroyo Mocho Trail, which stretches about five miles through the city and follows a winding, paved path alongside tree-lined creeks, under bridges and parallel to roads at different stretches along the trail.

The course heads west along the trail nearly all the way to Isabel Avenue and Stanley Boulevard. Runners make a brief couple of turns on Daisyfield Drive before turning back onto the Arroyo trail to head back in the opposite direction, which takes them past Hagemann Park, Mocho Park and Oak Knoll Cemetery on the way back to Robertson Park. Just before the turn into the park and Livermore Valley Stadium, the course instead continues on along the northern edge of Robertson along the Arroyo Mocho Trail, toward Concannon Boulevard.

It's along these miles back to the park that the gentle, gradual downhill descent that unfolded in the first few miles turns around and becomes a gradual uphill in the second half of the race, leading to the biggest hills of the race once runners make their way onto the trail sections that parallel Wente Street and Marina Avenue. The race reaches its peak in the stretch that runs through Holdener Park, as the course brings runners all the way through the park and continues on the trail just west of it, to the turnaround point and back.

The half marathon has a course time limit of 4 hours, and age group awards will be presented to the top 3 finishers in the following age divisions: age 19 and under, 20 to 29, 30 to 39, 40 to 49, 50 to 59, 60 to 69, and age 70 and above.
