45 upcoming Half Marathon races found · 7 with finish-time stats
Kansas City running is shaped by genuine variety underfoot. You can log street miles on the wide downtown boulevard grid, chase the fountains and foot traffic around Country Club Plaza, or duck into the forested dirt paths of Swope Park without leaving city limits. The Trolley Track Trail through Brookside and the Longview Lake Greenway give long-run legs real room to breathe.
Fall is when the city's race calendar gets serious, and the weather tends to cooperate - cool enough to push hard, with the kind of post-run culture around Midtown and Westport that makes hanging around afterward feel like part of the plan. Whatever your reason for toeing the line here, the half marathon distance has a race on the calendar to fit it.
By the numbers
The Kansas City races that stand out on the numbers: the biggest field, and the longest unbroken run of editions.
How we calculate these stats: RunSesh calculates these figures from the most recent published results of past editions, sourced from RunSignup. We show aggregates only: field size, winning and median times, and the cutoff. We never publish individual finisher tables. Last updated Sep 10, 2026.
Entry fees run from $30 to $50. The typical entry is $30, which is where most races on this calendar sit. Three races already have a price increase scheduled, so if you have your eye on something specific, registering sooner protects you from paying more.
31 of the 36 races say they give a shirt. The remaining 5 have published nothing about giveaways either way - that is missing information, not a guarantee there is nothing waiting at the finish line.
Fall, running September through November, is the busiest stretch with 16 races on the calendar - more than any other season. If your training block lands in summer, August is the single busiest month with 6 races. Spring is the quietest window, with just 1 race in March if you want a low-key option before the crowds return.
Most races here also offer a 5K and 10K on the same day, so if 13.1 miles feels like a stretch, you can step down a distance without losing the event experience. There are no published finish-time results across these races to draw on, so the best read on pace and atmosphere comes from checking individual race pages directly.
