    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 3.1 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 3.1 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!

    2026 official routes will be posted in March 2026. You can see last year’s routes below for an idea of what they might look like!

    Triathletes throughout Michigan have long considered the Island Lake State Recreation Area, home of the Island Lake Triathlon, an epic training destination, ideal for any athlete preparing for a multisport event. Set within a 4,000-acre park in Livingston County that offers an “up north” experience without leaving southeast Michigan. The terrain is a mixture of open brush land to mature hardwood forest, with some pockets of open meadows mixed in with a paved road of rolling hills weaving throughout. You’ll swim the clear waters of Kent Lake, bike the park’s rolling, tree-lined hills, then run the panoramic final leg towards the lakeside finish line!

    Island Lake Tri features 7 different events:

    Olympic Triathlon — 1500 meter swim, 24-mile bike, 6.2-mile run

    Sprint Triathlon — 750-meter swim (32 lengths in a standard metric pool), 12-mile bike ride, 3.1-mile run

    Mini-Sprint Triathlon — 400-meter swim (16 lengths in a standard metric pool), 12-mile bike ride, 1.5-mile run
