About
The Garmin Olathe Marathon, Half Marathon and 10K takes place in Olathe, Kansas, in late April, and is organized by Garmin at its headquarters. It features a marathon (26.2 miles) and a half marathon (13.1 miles) starting at 6:45 AM, a 10K (6.2 miles) at 7:00 AM and a family-friendly Munchkin Run of about 1.2 miles at 8:30 AM. The courses use the city's streets and trails and show off Olathe's closeness to Kansas City and the charm of the Midwest. With early starts and spring weather that can change quickly in Kansas, it is smart to check the forecast and keep a spare layer in your bag.
