Palo Alto 10K, 5K Run/Walk and Double 15K

Take on a unique pre-holiday challenge at the Double Racing® Palo Alto event, in Palo Alto, California, home to the signature Double 15K: a two-stage timed race — a 10K followed by a break, then a 5K — with results based on combined finish times. Runners of all levels can also choose a standalone 10K, a 5K run/walk, or Bob Anderson's Kids Mile, open to children 13 and under.

Courses are flat, fast, and fully paved, winding through the peaceful Palo Alto Baylands, one of the San Francisco Bay's richest wetland ecosystems. Created in 2012, this family-friendly event tests runners' pacing strategy and recovery.
