About the event

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.

Not ready to attempt the Ultra-Distance race? Michigan Titanium offers Half, Olympic and (NEW) Sprint distances in our Triathlon, Duathlon, Aquabike, Relay & Swim-Only events.
