Navy Ten-Miler

Navy Ten-Miler is held in Chula Vista, California on February 28, 2027. The Touch-n-Go Half Challenge, which covers half marathon distance (13.1 miles), and the NTM 5K both start at 7:30 a.m., the Navy Ten-Miler itself follows at 8:30 a.m. over 10 miles, and an NTM Youth Run over 1 mile closes the morning at 10:00 a.m.

The ten-mile distance deserves more attention than it gets. It is long enough to demand real aerobic fitness but short enough to race at close to threshold effort, which makes it an excellent bridge between a 10K and a first half marathon. Ten weeks of consistent running with a long run of 8 to 10 miles will have you ready. Runners who want the full 13.1 can take the Half Challenge instead, while the 5K and the youth run keep the event open to families and newer runners.
