The Tri Up North triathlons are bike, paddle, run triathlons in Frankfort put on by the Paul Oliver Memorial Hospital Auxiliary. This event centers around Frankfort's Betsie Bay on the Western shore of Lake Michigan which is the perfect setting for a triathlon. Tri Up North features two different triathlon courses: the Classic 10 mile event, which is specifically geared toward beginners and those who are looking for a little motivation to become more active, and the Challenger 22 mile event, which is a competitive course for experienced athletes and relay teams looking for a challenge. For those who would like to participate but aren't interested in tackling a triathlon, there is the Betsie Bay Walk. This fun non-timed 2.5 mile walk may be the perfect fit!
