Love running half marathons? This Kansas City series is ideal for you! Tackle three separate races between April and May 2026—Rock the Parkway Half Marathon, Garmin Olathe Half Marathon, and Hospital Hill Run Half Marathon—where you can race each one independently while also competing for the best combined time across all three, earning special series completion rewards. The series price matches what you'd pay registering for each race individually, and if you've already entered any of them, reach out to Amy at KC Running Company to get a discount code applied to your account.
