Irving Frost Marathon

Irving Frost Marathon is a winter race in Irving, Texas, based at the Toyota Music Factory, on December 19, 2026. The marathon (26.2 miles) and the half marathon (13.1 miles) start at 7:30 a.m., the 10K at 7:45 a.m. and the 5K at 8 a.m. The courses are USATF-certified, flat and fast, and the event supports the Irving Schools Foundation. Entrants get a race shirt, a personalised bib, free professional photos and live tracking, with cash prizes on offer and a post-race party with entertainment, food and free beer.

A certified, flat course is exactly where you attempt a qualifying time or a personal best, because the distance is honest and nothing on the profile makes excuses for you. For the marathon, that means sixteen to eighteen weeks of building, a long run reaching 20 miles, and goal-pace work so the effort is already familiar.
