Whether you are a first timer or a seasoned triathlete, come take part in the TriMuskokan. This grassroots homegrown event is an incredible community event that focuses on a great experience for everyone!
Whether this is your first triathlon or you are an experienced athlete, The TriMuskokan has something for everyone.
If you have never done a triathlon or a duathlon before, or are just starting out, a nice way to try out an event is through a relay. These are fun ways to be active with a group of friends…pit one team against another for bragging rights, or for who has to cook the celebratory dinner!
If you don’t like swimming, try the duathlon. If running is not your thing, try the swim/bike event!
The TriMuskokan offers the best of grassroots racing in a professionally run event.
Race Information
