Frank A. Theis Park turns into a staging ground for roughly 11,000 runners early Saturday morning as the Garmin Kansas City Marathon kicks off its full slate of races across the city. The full and half marathons launch together at 7 a.m., with the 10K following at 7:30 a.m. and the 5K rounding things out at 7:45 a.m., all starting and finishing at the park across from the Nelson-Atkins Museum of Art.
Organizers expect the field to break down into about 2,500 full marathon runners, 5,500 half marathoners, 1,500 in the 10K, and 1,500 in the 5K, according to the Kansas City Sports Commission. The full marathon field is less than half the size of the half marathon turnout, reflecting the shorter distance's broader appeal among the weekend's participants. For runners and spectators plotting their routes, the Kansas City Star has published course maps covering all four distances.
A Hilly, Record-Eligible Course
Runners tackling the full 26.2-mile marathon face a punishing elevation profile, including an immediate 100-foot climb within the first 1.5 miles. In total, the course carries about 1,050 feet of combined elevation gain and loss, per the commission's race FAQ, as it winds through paved boulevards, downtown blocks, and historic neighborhoods. The half marathon covers 13.1 miles.
Despite the physical demands, the course carries real competitive weight. The full marathon route is certified by USA Track & Field and serves as an official Boston Marathon qualifier, meaning finish times here can open the door to one of distance running's most selective races. The race starts, takes place, and finishes in Missouri, even though greater Kansas City straddles the state line into Kansas.
Getting There Without Adding to Race-Morning Gridlock
Race-day street closures are expected.
The Garmin Kansas City Marathon is organized by the Greater Kansas City Sports Commission & Foundation, a privately funded non-profit that also handles civic sporting initiatives including Big 12 tournament hosting duties, according to Endurance Sportswire. Last October, the foundation struck a partnership with global platform GoFundraise, giving runners tools to build their own charitable fundraising campaigns tied to their race entries as part of the event's peer-to-peer giving push.
A Cross-State Running Partnership
This year's event also ties into the I-35 Challenge, a partnership with Iowa's IMT Des Moines Marathon that lets runners complete two distances at races in both cities on back-to-back weekends. Finishers who complete both events earn specialized extra medals and gear, according to event details published by Planomato.
