The Scene

Michigan's newest state park, Belle Isle sets the scene for arguably the fastest triathlon course in the entire country. If you’re looking for a PR, this is the place to do it!

New for 2016 and 2017, and specifically for the Motor City Triathlon, the entire south end of the island will be closed to traffic – in other words, a closed course. Music to the ears of the triathlete who doesn’t want to worry about cars and spectators during the event. Those who have competed here in the past know the Detroit International Grand Prix is typically a few weeks before our event, and the entire island is open for the Motor City Tri. This year and next, due to the way Memorial Day weekend falls, the Grand Prix will be 6 days prior. So the entire south end of the island will be closed and off limits to the public. A HUGE THANK YOU to the folks at the Detroit Grand Prix for making accommodations for the 12th & 13th Motor City Triathlons to remain on our date.

No traffic on half the bike course, and half the run course too. A barricade will be opened and manned by DNR officers at the bike entry / exit point as well as the run entry / exit point. So in a sense, we have our own private venue for the event. This means you must pay attention to course and venue maps as well as support crew when arriving on the island. Half the island will be closed, so it’s different than what you’ve been used to the past 11 years.

Again we can't thank the folks at the Grand Prix enough for working with us. Their cooperation has allowed our event to be even better for the athletes this year and next. This is going to be great!

Multi-Sport 101
Multi-Sport 101 starts 2:00pm in Transition 2  

Geared toward the newbie, but enough information and tips for the savvy veteran.  We were the first to host multi-sport 101 before events, starting over 10 years ago. Now most quality events have some version, but we have been told by athletes across the country that our multi-sport 101 is the best.  The race director will walk you through the entire event, start to finish, answering your questions along the way and giving you tips. 

The goal with every class is to calm down those pre-race butterflies and reduce some of the anxiety, so you can sleep a little easier the night before your big event.  We will start from the time you arrive onsite through your departure following your big finish.  Please check the week of the event for potential time changes on class. Each class is weather permitting.  Classes will typically run between 45 to 90 minutes, depending on questions and the event. Occasionally we will have a special guest as well.


Proceed to Central Street for Parking ONLY.  
Follow all signs for parking, Absolutely DO NOT park where NO Parking signs are posted, please do not move cones and there is NO Parking on Picnic Way, that is the run course!

Athletes Responsibility

bopsuperstar EventDue to an increasing amount of athletes entering events they may not be properly trained for, we are asking each athlete to be responsible and honest with his/her ability to complete the distance registering for.  Due to safety concerns for everyone involved including you the athlete, but also the support crew volunteers and officials like police, sheriff, fire department, etc. we must instill course cut off times at 4 hrs.  Raffle and awards start at 3 hrs and 30 minutes in Olympic distance events and 99% of all athletes are finished by that time. So you must register for the event you will finish under that 4 hour time limit.  Being a responsible athlete means if you cannot complete the Olympic distance comfortably under that time we recommend you participate in the sprint event.  We encourage you to train for the goal to reach that Olympic distance under the 4 hour time limit.  If you do not have a clear idea as to how to achieve that goal we are here to help, please let us know.

An athlete will be informed he/she has reached the 4 hr. cut off, at which time the athlete will acknowledge he/she understands completely and he/she will be brought in off the course by the course coordinator.  If the athlete refuses this he/she will be informed that there will not be any support left on the course from that point and he/she must acknowledge this and understand he/she is continuing under those circumstances at which time the athlete will remove the timing chip/strap and give to the course coordinator.  

Again an athlete must take the responsibility on as an athlete understanding his / her ability at the time of the event.  Knowing that support crew volunteers, as well as other personnel out on courses must be kept in safe conditions as well.
