Zoom Quarry Lakes Half Marathon, 10K & 5K

Saturday, June, 2018 • Fremont, CA • Course Map

Giving runners a taste of the trails, the Zoom Quarry Lakes Half Marathon in Fremont, California is the perfect introduction for those looking to get off the asphalt — along a route that’s identical to the one run at December’s ZombieRunner Quarry Lakes Run.

Featuring 64 percent of the course on crushed rock and 36 percent on pavement, this race is a great in between for road runners and trail runners alike. With just 30 feet of elevation gain over the course of the race, expect this trail run to be fast and fun.

Runners will take advantage of the Quarry Lakes Regional Recreational area and follow the Alameda Creek Trail up to the mouth of the Niles Canyon. At 9:00 AM, the half marathoners will follow the 10K course that travels around the lakes heading west. The course takes runners past Shinn Pond and travels along the Alameda Creek until reaching Old Canyon Road.

Once at the turnaround at Old Canyon Road, runners travel back along the Alameda Creek and cross back by the Quarry Lakes. Once beyond the Quarry Lakes area, racers will stay on the north side of the creek until reaching Alvarado Boulevard. The course then travels on the south side of the creek all the way back to the Quarry Lakes area and the finish line.

A total of five aid stations are located along the course at Niles Canyon, Wood Duck, Arizona, Beard Staging, and Wood Duck (again). Water and sports drinks will be offered along with candy, salty snacks, and fruit.

The top male and female runners will receive awards along with the top three in each age category. All finishers will receive a medal upon crossing the finish line. Runners will have 3 1/2 hours to complete the course.
