Garmin Olathe Marathon, Half Marathon & 10K in the Land of Oz

Saturday, April 20, 2024 • Olathe, KSCourse Map

Take a running tour of the history of the settling of the American west in all three races at the Garmin Marathon in the Land of Oz — officially titled the Garmin Olathe Marathon, the Garmin Half Marathon and 10K.

Fast and largely flat — there are some rolling hills along the course, but the elevation changes for most are mild — the out-and-back course for the half marathon offers a perfect route for runners of widely varying abilities.

The starting time for the half marathon (and the full marathon, which shares the same starting location) is 6:45 AM, and shuttle bus transportation to the starting line will be provided.

The half-marathon course, which unfolds along the first dozen miles of the marathon course and is paved throughout, starts in downtown Olathe along East 151st Street.

From there, the course ventures eastward and then northward, following a somewhat zigzag course through the city on its way toward sights like Waterworks Park, which runners run past, Naval Air Park and the Great Mall of the Great Plains.

Walkers are welcome, provided they can finish the course within six hours, an achievable pace for the half marathon.

Race Weather & Climate

The spring season in the Olathe area, which lies in the northeast corner of the state and is considered a suburb of nearby Kansas City (Missouri), tends to be highly variable, so race organizers advise participants to arrive with adequate clothing for all weather conditions.

On race day (Apr. 20), the average low is 43ºF and the average high is 56ºF.
