From the Organizer
There are seven days in a week and “someday” isn’t one of them. Make the commitment to become a triathlete or duathlete today! The Shawnee Mission Triathlon & Duathlon takes athletes throughout the most visited park in the state that serves as a 1,250-acre urban refuge. Additionally, the course joins the Mill Creek Streamway Trail offering asphalt pathways snaking along the stream and through hillside forests. With five different events including relays, there is something for every athlete ranging in experience from first timer to the seasoned veteran. The Shawnee Mission Triathlon & Duathlon is featured as the USA Triathlon Kansas State Championship event with the top 35% of finishers in the Short Course and Olympic Triathlons qualifying for USA Triathlon Nationals.
COURSE OPTIONS
The duathlon race begins on the main park road near the check-in tent. The run segments will take place on the main park road and the Mill Creek Streamway Trail. The first run course will be in a loop going in a counterclockwise direction, and the second run course will be the same loop but in a clockwise direction. The bike segment will consist of three laps around the park on the main park road.

From Endurance Grid
This race spans more than one sport — here’s a guide to each, so you can understand what’s involved and decide if it’s the right fit. For course distances, logistics, and race-day specifics, always defer to the race organizer’s event page.
Swim, bike, run — back to back. The sprint distance makes it far more accessible than most people think. Three sports in one race means three movements to train and race day never gets monotonous.
Run, bike, run. The multi-sport format without the swim. Two disciplines, one race — a great bridge between running and triathlon.
