TriWalloon
About this race
Welcome to TriWalloon, a triathlon staged in the increasingly popular Walloon Village. The pristine waters of Walloon Lake are located between Petoskey and Boyne City, Michigan and offer a stunning setting for a triathlon. The event consists of a sprint distance triathlon, duathlon, and aquabike. Our races have proven to be a great event for all, from the beginner athlete who wants to attempt their first triathlon, to the seasoned and elite athletes who race every weekend. Relay teams are also encouraged for the triathlon. Male, female and co-ed are welcomed. This event will make for the ideal destination race for all. Come for the race, stay for the weekend!
TriWalloon has become a favorite with many multi-sport athletes from around the state. We started in 2017 with 120 athletes. Now, just a few years later we sell out with over 350 athletes registering each year.
COURSE DESCRIPTION:
600 Meter triangular swim course starting and finishing at the docks of Legacy Marina. Transition area is right out of the water in the park next to Barrel Back Restaurant. The bike course is a 12.4 mile out-and-back route that follows the country roads along the south side of Walloon Lake. The run is a two-loop course through Walloon Lake Township, with a finish back at the park next to Legacy Marina.
Duathlon will start with one loop of the run course, then bike, then finishing with the full, two-loop run course.
Aquabike will start with the 600m swim and finish after the bike course.
Once again, 100% of the proceeds from this race will go toward the continued work of the inner-city ministry of Bridge Street Ministries. Please visit bsmgr.org for more information about this great mission.
