The Holiday Half Marathon!

The Holiday Half Marathon! is run in Pomona, California, on December 13, 2026, inside a public park. Two road formats are offered, a 5K and a half marathon (13.1 miles), so you can pick the one that matches the training you have actually done. The green parkland setting on the edge of the greater Los Angeles area gives the race a different feel from a downtown street event.

If the half is your goal, plan on a 12- to 16-week build with a weekly long run that climbs to 11 or 12 miles, plus one steady tempo run a week to teach your legs the pace. The 5K asks far less of your calendar: a month of regular running is enough to line up, and it makes a good first race or a fast finish to the year. Both distances share the same park, so supporters can watch either one.
