Michigan’s Only 140.6 Mile (Ultra-Distance) Triathlon
140.6 miles: that is what you are up against. Start your challenge with a 2.4-mile swim in crystal-clear Versluis Lake. Then, jump on your bike for 112 miles through the rolling countryside of West Michigan. Finish up your day with a full marathon on the closed run course. Do all that and cross the Michigan Titanium finish line… and you’ve earned the right to call yourself a TITAN.
Are you not ready to attempt the Ultra-Distance race? Michigan Titanium offers Half, Olympic, and Sprint distances in our Triathlon, Duathlon, Aquabike, Relay, and swim-only events. There is an event and distance for everyone at MiTi!
