Garmin Kansas City Marathon
Kansas City, United States · Saturday 17 October 2026
The Garmin Kansas City Marathon takes runners through the heart of Kansas City, a region known for its rolling terrain and varied landscape. Situated in the central United States, the course winds through areas that showcase the character of the region, with elevation ranging between roughly 230 and 300 meters above sea level. The October timing means runners will experience fall conditions typical of the Midwest, which can offer pleasant racing weather depending on the year. This is a trail marathon with moderate hills throughout, so pace yourself accordingly. The course gains around 300 meters of elevation across the 42.2 kilometers, which means you'll encounter a mix of climbs and descents rather than the consistent grinding you'd face on a steeper route. The terrain itself is trail-based, so expect natural surfaces that demand more from your legs than road running would. The rolling character of the course means few truly flat sections, but the hills are distributed across the race rather than clustered, which helps spread the effort. Runners should prepare for the demands of trail running, including uneven footing and the mental challenge of sustained elevation change, and come ready for whatever autumn weather Kansas City throws at you.
