Garmin Olathe Marathon, Half Marathon and 10K in the land of Oz

Lace up your running shoes for the Garmin Olathe Marathon, Half Marathon, and 10K in the Land of Oz, taking place on April 25, 2026, in Olathe, Kansas. Celebrating its 23rd anniversary, this event offers a full marathon (26.2M), half marathon (13.1M), 10K (6.2M), and a spirited Munchkin Run (1.2M), all starting and finishing at the Garmin World Headquarters. The course provides a unique tour through Olathe's streets and paved trails, described as generally flat with some rolling hills, particularly noticeable around miles 7-13 and a more significant elevation change near mile 15 of the marathon. Runners can anticipate a scenic stretch along a paved bike trail from approximately miles 15 to 25, offering a refreshing view amidst urban landscapes.

Experience the Midwest charm with a touch of magic, as the race embraces its beloved Wizard of Oz theme, often featuring new characters each year. This well-organized race is known for its runner-friendly logistics, including easy parking at the Garmin HQ, a small but sufficient expo, and enthusiastic local support. Aid stations are strategically placed every 1.5 to 2.5 miles, providing water, Gatorade, and GU at select stops, along with readily available porta-potties. Post-race, participants are treated to a lively atmosphere with ample food like bagels, granola bars, and bananas, plus an impressive selection of beer, and coveted finisher medals and soft t-shirts. Typical race day conditions in late April offer ideal running weather, with historical highs around 66°F and lows around 47°F, and only an 18% chance of precipitation, setting the stage for a memorable and potentially fast race.
