Holiday 5K, 10K, & 13.1M at Kansas City, MO

Holiday 5K, 10K, & 13.1M at Kansas City, MO is run in Kansas City, Missouri, on December 26, 2026. The half marathon (13.1 miles), the 10K and the 5K all go off at 8 a.m. on scenic routes chosen to highlight the character of the city. Finishers collect a medal, and the event invites runners to turn up in their best holiday costume, with prizes on offer for the ones that stand out.

Costumes and a personal best rarely go together, so decide which one you are there for before race morning. If it is the time, the half rewards a twelve-week build with one weekly long run and a couple of sessions at goal pace. If it is the costume, the 5K keeps the outfit intact and the morning short. The 10K sits between the two and is often the best use of a holiday week, long enough to matter and short enough to recover from by evening.
