Half Marathons in January 2027

January half marathons follow the sun. Houston's Aramco Half runs alongside the Chevron Houston Marathon on a fast, flat course, Carlsbad sends runners along the Southern California coast, and Phoenix kicks off Arizona's desert racing season. A January half is a good way to start the year with a goal, or to check your fitness before a spring marathon.

Racing in January? Start our 12-week half marathon training plan around late October.
