From the Organizer

RUN the scenic river trail
PADDLE the beautiful Shiawassee River
RIDE  through city streets and country roads

The mission of the Shi~Tri is to promote community fitness, provide a fun and challenging race that anyone can do and to support the work of the Friends of the Shiawassee River in their effort to share, care for and promote the enjoyment of the Shiawassee River. 

The Shi-Tri is a Run/Paddle/Bike Triathlon beginning and ending in Downtown Owosso, MI along the beautiful Shiawassee River. Participants begin with an approximately 3.3 mile run/walk from downtown Owosso to McCurdy Park in Corunna. From there, you will launch your kayak or canoe into the river and paddle about 3.3 miles back to Owosso where you will then bike a ~9-mile loop through city streets and country roads.

This event can be completed by ANYONE! Treat it as a race and challenge yourself for a new personal best. Or, take your time and walk the river trail, float peacefully in your kayak or canoe and bike leisurely while enjoying the beautiful outdoors. You can even team up with friends to create a relay, divvy up the legs of the race, and complete it together!

An event like this also relies on the efforts of over 100, valued volunteers! Come join us in this wonderful, community-oriented experience as a volunteer-bring your family and friends! 

2027 official routes will be posted in March 2027. You can see last year’s routes below for an idea of what they might look like!
