5K for Fragile X

5K for Fragile X is held in San Dimas, California, on Saturday, April 17, 2027. The event offers a single format, a 5K run/walk (3.1 miles), starting at 9:00 a.m. Because walkers are explicitly welcome alongside runners, the start line usually mixes people chasing a time with families out for the morning.

Run/walk 5Ks are the easiest way into road racing. If you have never raced, you can be ready in about six weeks by running or walking three times a week and gradually stretching one of those outings toward 3 miles. If you already train regularly, this is a chance to test your current 5K fitness: a short warm-up, a controlled first mile and a hard last kilometer will tell you more than any workout. With a 9:00 a.m. start you have time to jog, drink and line up without rushing.
