The mission of the Shi~Tri is to promote community fitness and to support The Friends of the Shiawassee River. Proceeds from this year’s events will be put toward river improvements designed to help everyone Care, Share and Enjoy our treasured 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 a 3.8-mile run/walk from the Fitness Coliseum Downtown (210 S Water St, Owosso) to McCurdy Park in Corunna. From there, you will launch your kayak or canoe into the river and paddle 3.5 miles back to Downtown 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! Registration is open for everyone interested at

Members of a relay team (2 or 3 people) will complete one or two legs of the race while their team members complete the others, to collectively complete all three legs. 

Any type of registration can be a part of a team! Companies, sports teams, organizations, families, ANYONE can create a team! Have your teams first registrant set up your team name or email it to and we will get it all set up for you! Registering under a team ensures that your transition areas (kayak and bike locations) will all be grouped together!

The youth participant will NOT be allowed to begin the next leg of the race without the adult participant with them. 

Each adult participant MUST have a life vest with them in their kayak. Presence of a life vest will be verified in the staging area and checked again prior to launch. All youth participants are required to be WEARING their life vest for the duration of the paddle leg of the race. 

Sorry, there will be no refunds for this race. You are able to purchase race insurance via the RunSignUp website when you register.

We apologize for any inconvenience

Training/Race Prep

Run – This run leg of the Shi~Tri is 3.5 miles long, just slightly longer than your traditional 5k. The course is along the river, so expect some slight twists, turns and uneven surfaces though the course is relatively flat. Work your way up to completing this distance with any combination of a run/walk!

Kayak – The kayak leg of the Shi~Tri is 3.5 miles downriver. Downriver means you can float, and still go in the correct direction, if you do need a break from paddling during this leg! We do recommend that you have some practice launching, getting in, getting out and pulling out your kayak from the river, as this can be a bit difficult! Learning to navigate your kayak away from banks will also be a necessary skill.

Bike – The bike leg of the Shi~Tri is a 9 mile out and back on paved, flat roads. Ensure your bike is in good enough condition to complete this distance.  Ensure you are able to complete this distance on your bike and have done some rides with wind as a factor. Much of the bike loop has open fields on one or both sides of the road, meaning a windy day will add some difficulty to the course.


We will need MANY volunteers for this event! From working the registration table, handing out water, directing participants on the run and bike, and helping to move and launch kayaks, we need all the help we can get!
