2026 Kansas City Marathon - Oct 17 Countdown

Q: When is the 2026 Kansas City Marathon and what time does it start?

The 2026 Garmin Kansas City Marathon is on Saturday, October 17, 2026 — the race traditionally falls on the third Saturday in October. The full marathon and half marathon start together at 7:00 a.m. Central Time near Crown Center and the Liberty Memorial in midtown Kansas City, with the 10K at about 7:30 a.m. and the 5K at 7:45 a.m. It is organized by the Kansas City Sports Commission &amp; WIN for KC.

Q: How hilly or hard is the Kansas City Marathon course?

It is a rolling, moderately hard course, not a flat speedway. Total elevation gain is roughly +1,200 ft (about 365 m), with the single toughest climb in the first 1.5 miles and rolling hills throughout, plus a punchy rise back toward the Liberty Memorial near the finish. It is scenic and runnable, but plan for the hills rather than expecting an easy personal best — our pace calculator helps you plan a realistic effort.

Q: Is the Kansas City Marathon a Boston qualifier?

Yes. The course is USATF-certified and accepted as a Boston qualifier, so a fast enough time here counts toward Boston Marathon entry. That said, the rolling terrain means it is a harder place to run a qualifying time than a flat, fast course, so target it knowing the hills will cost you a little. Check the standard for your age and gender with our Boston qualifying calculator.

Q: What is the time limit for the Kansas City Marathon?

The full marathon has a 6-hour time limit, which works out to at least a 14:00 per mile (about 8:42 per km) pace; the marathon course officially closes around 1:00 p.m. and all on-course support ends by about 1:45 p.m. Runners who fall behind that pace may be asked to move to the sidewalks and continue at their own risk without race support. Our finish time calculator helps you check your projected pace.

Q: How do I register for the 2026 Kansas City Marathon and what does it cost?

Registration is handled online through RunSignUp, linked from the official site at sportkc.org. The full marathon is around $130, with the price increasing after late July 2026, so registering early saves money. The weekend also includes a half marathon, 10K, 5K and virtual options; packet pickup is at the pre-race expo, with no race-morning bib pickup for the marathon.

Q: What is the weather like for the Kansas City Marathon in October?

Mid-October in Kansas City is usually cool and crisp — some of the best racing weather of the year. Expect a start around 50°F (10°C) at the 7 a.m. gun, warming into the mid-to-upper 60s°F (about 18-20°C) by midday, with moderate humidity and a chance of fall foliage along the route. Dress for the chilly start with layers you can shed.

Wind Impact on Race Day

Wind at 25.1 km/h can affect your marathon pace by 5-15 seconds per kilometer. Headwinds slow you down exponentially — a 20 km/h wind costs more than twice a 10 km/h wind.

Terrain	Road (rolling city streets, boulevards and park drives through midtown Kansas City)
Profile	The Garmin Kansas City Marathon is a genuinely scenic metropolitan tour rather than a flat PR machine — and it is honest about its hills. Starting and finishing near Crown Center and the Liberty Memorial in midtown, the USATF-certified course rolls through some of Kansas City's most photogenic districts: the Spanish- and Sevillian-styled Country Club Plaza with its fountains and tile rooftops (Kansas City is the self-styled 'City of Fountains'), the museums and boulevards of the Plaza-Westport area, leafy neighborhoods like Hyde Park, and the climb up to the National WWI Museum and Liberty Memorial tower, which rewards runners with a panoramic skyline view. It is a rolling, moderately hard course: total climb is roughly +1,200 ft (about 365 m), with the toughest sustained hill in the first 1.5 miles and rolling terrain throughout, including a punchy climb back toward the memorial near the finish. It is a Boston-qualifier-eligible course (USATF-certified), but the rolling profile makes it more an experience-and-effort marathon than a guaranteed personal best — train for the hills.
