The swim course has worked really well with the MI Championships in the past, so that will be unchanged.

The bike is lightning fast – arguably one of the fastest courses in the country – as you get the wind either on the Canada side or U.S. side of the island which enables you to reach speeds over 30 mph. It is closed to traffic with coned lanes around the entire island. The difference will be you will enter after completing your laps on the East side of the island at the fountain way drive. This will be indicated by a bike-in structure.  

The run course is flat as well and the will loop take you across 4 bridges two on the south end and two back in the nature trail.  It is a tad more than a 5k/10k being at 3.3 and 6.6.  



TRIATHLETES:  RUN GEAR ONLY at T-2! Swim and Bike gear at T-1.

DUATHLETES ONLY: You must keep your bike gear at T-2

This event will have two transition areas because the beach is one mile from the finish line, parking area, and T-2 located at Shelter #1.  PLEASE park at T-2/finish line, on Central.  Then go set your running gear and ride your bike to T-1.  Again PLEASE DO NOT drive down to the swim start, T-1.  We will transfer your gear from T-1 to T-2.  So when you finish it will be ready for your pick up.  It is YOUR responsibility to label your equipment bag with your name and RACE #.  We are absolutely NOT responsible for any lost items.  Do not put valuables, keys, etc, in your gear bags for transport back to T-2.  TIP:  Use a bright colored bag that sticks out.  There are 500 plus other gear bags at pick up.

Again, it is YOUR responsibility to bring a gear bag and mark it with YOUR RACE # and name.  We will not be providing bags.  Anything not put in a bag will be put in a general pile.

CHIP PICKUP will be at T-2 and Body Marking will be at T-1 near the RUN IN CHUTE.

Repeat, CHIP PICK-UP will be at T-2 (shelter #1, finish line, registration area).

Transition area #2 will be on the large cement pad in front of Shelter 1.  When arriving on the island follow signs and support crew.  Again you must park here, place your RUN gear in transition, receive your timing chip and strap, place that on your ankle immediately and head to T-1 with the rest of your race gear.  (Race Management will not be responsible for any unbagged or unclaimed race gear; please make sure your bags are marked).

Following the last athlete exiting T-1, all gear bags will be taken to the finish gear bag claim area at T-2 just past the finish line along the transition area.  You must have your race number to claim your gear bag.  Sprint athletes, please give support crew time to sort and organize bags.  To expedite loading trucks with bags, athletes should carry their own bag out of transition and toss it in the pile at exit.

Opens – 5:30 am
No friends or family members allowed in the transition area for any reason.  The race director and race officials will close the transition area 30-45 minutes before race start to ensure all athletes are at the starting area for mandatory course meeting and announcements.  Once the transition area is closed, you will NOT be permitted back in before the race starts.  Family/Friends will not be permitted in for any reason at any time throughout the event.

When the last cyclist is off the course and has headed out for the run.  This time is variable and we will make announcements at the event when the transition area is ready to re-open.

Any athletes removing gear from transition areas before the announcer or race director has officially opened the transition area will be DISQUALIFIED from the race!  This pertains to all athletes of all distances.  All athletes deserve a clear transition.

In the event of inclement weather, it is recommended you have warm, dry clothing outside the transition area to put on following your finish due to other athletes still being on the bike course.

Timing Chip
When you have completed the race, please do NOT enter the transition area wearing your timing chip.  PLEASE remove your chip before re-entering the transition area and exiting again.  This will cause a timing error.

You must rack according to your race number, based on the sequence numbers placed at the end of each row.  Please remember racks will hold 7 bikes racked with the seat tip on support bar.  Please be courteous to fellow athletes to ensure there is space for 7 bikes on a rack.  If there is not enough room for your bike on your designated rack, please see a 3D Team member and we will help.  Please do not move another athletes bike or gear.

Aid Station
Located at the run in/out chute with water and electrolyte replacement.

Run In/Out and Bike In/Out chutes are clearly marked on the large structures at either end.   It is your responsibility to go the right direction while racing in the transition area.

Swim: 200m, 500m or 1.5k

The swim begins at Belle Isle Beach, on the Detroit River at the edge of Lake St. Clair.

New for all events will be a Time Trial swim start.  For safety reasons it is important we ensure we are doing all we can to alleviate stress at the start and turning at buoys.  A time trial start ensures everyone has a clear, stress-free swim.  You will SELF SEED according to your 500m swim time.  (THIS IS YOUR ACTUAL swim time, not what you THINK you will swim, or want to swim). This is important to ensure you are not swam over or create congestion by seeding yourself faster than you can swim.  Don’t be that athlete that creates a traffic jam.  Seed yourself appropriately and everyone will have a great time in the water.

Each athlete will report their number to the timer before crossing the timing mats and entering the water.  Again your responsibility to report that number to the timer.

Time trial starts: Long course athletes first, followed about 30 minutes later with Sprint, then 20 minutes later Super Sprint athletes.

Contrary to popular belief, this is some of the cleanest tested water in the entire state because of the current. There is a constant “flush” here with currents of 7 plus mph. You swim in crystal clear water with the modified triangle swim. We keep you right on the edge of the current, so you will have a pretty fast swim, but the key is to navigate that final turn heading to shore.

Water temp has typically been between 65 and 75.

Wetsuits will be allowed.

Bike: 5.7 mi, 11.4 mi or 22.8 mi

Exiting Transition 1 at the beach, you merge into the inside lane which is coned all the way around the island.  As you pass the Transition 2 with each lap you will see the “OFF RAMP” you will take when you have completed your 1, 2 or 4 laps of the island.  There are no turns, you simply use the bike lane or inside car lane all the way around the island.  

Super Sprint athletes will complete 1 full lap with an additional mile to get back down to Transition 2 at the Casino/Finish/Registration area.

Sprint athletes and Duathletes will complete 2 full laps with an additional mile to get back down to Transition 2 at the Casino/Finish/Registration area.

Olympic Distance athletes will complete 4 full laps with an additional mile to get back down to Transition 2 at the Casino/Finish/Registration area.

Slower athletes PLEASE STAY ALONG THE CURB ON THE INSIDE OF THE ISLAND; faster athletes will stay along the cones, outside of the island.

You will enter after completing 2 or 4 complete loops of the island at Fountain Way, under the bike in structure, and proceed to T-2 at the Casino.

 Exiting Transition 2 at the back side to straight across into pitway, then straight to the south end of the island, around, then a LEFT to the great fountain, around and backup pitway.  Then over to the casino, across the bridge and back towards the venue.  You will see the finish line and hear the music at this point before running up the walkpath to a down and back, before heading out to central for about a 400m straight jet to the finish line.

You will start with your specific swim wave. Check the information cube at the event for wave start information.

You will complete the Swim and Bike disciplines of the event. Following your Bike discipline, you will dismount your bike, cross the Bike In timing mats and place your bike back at your spot on the rack in the Transition Area.  You will then proceed across the Run Out timing mats and you are done! Your finish time will be when you cross the timing mats at that point.

DO NOT re-enter the transition area through Run In/Out or Bike In/Out. This will cause a timing error.

Finisher Memento 
If the event offers a finisher’s memento, please proceed to the finish area to receive the item. Tell the support crew at the finish line you were in the aquabike race and they will hand you the finishers memento.

You will keep your timing chip & strap on until all the bikes are off the course. Once we announce the transition is open, you may turn your chip & strap in at the designated collection point and retrieve your gear at that point.

Super Sprint TRI

One of the first to launch the Super Sprint back in 2014, the goal with it was to provide an intro to Triathlon.  No matter your age, 6 yrs to 80+ yrs. the final wave of the day to start gets you out of the chaos of the start, and keeps you with like-minded athletes.  A perfect introductory distance that we try to keep non-competitive with no awards, but of course, everyone gets a finisher medal.  Come on out and Try your first TRI.  Questions, don’t hesitate, any question is a good question!

200m swim – your swim will always start following the final sprint athlete in every super sprint event.  These will be an out to the first buoy, over and in.

10k  bike – will be an out and back.  Following all signs indicating SUPER

1 mile run – will be an out and back as well.  Following all signs indicating SUPER


Starting with a 2.5k run.  FIRST and Most Important: this is a 2 transition event, so you MUST leave your BIKE GEAR and 2nd Run Gear at TRANSITION 2 (finish line, checkin area) not at the beach!!  

You will start at the Duathlon start flag across the street from the beach and Transition 1 on the corner.  About 5-10 minutes before your start announcements will be made to report to the start flag where the Run Course coordinator will be waiting to give you further instructions.  He/She will lead out the first run, which will take you back down to Transition 2, where you will head into transition and out on the bike course.  You will complete 2 loops of the island before heading back into Transition 2 again, where you will grab your run gear for the final 5k.  

Again, make sure you leave your bike and run #2 gear at the finish / Transition 2.  Do not take it down to the beach.  Then report to the start at the beach by 7:00 a.m.
