This course has remained unchanged for years. Athletes return year after year because it is truly a great course and a perfect test before the season really kicks in. The swim is along the dam so friends, family and spectators can watch the athletes as they navigate the straight out and back buoys. 

The bike course is a fast and flat out and back course. Sprint athletes have a pancake flat course, Olympic athletes get one nice climb, just to keep everyone honest out there. It is a quick out of your seat heart pounder, but only about 50m long. 

The run course is one of our favorite, though it has very little shade. It is one mile across the dam, then a nice little hill to the sprint turnaround, and back. Olympic distance athletes keep going to their 5000m turnaround point out past the next dam. The whole run is basically along the lake. When you reach the return dam and start to hear the music, you can hit the turbo button to get to the finish line right inside the park.

Transition Area

Opens - 6:00am 
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.

Transition Area Map

Swim: 200m, 500m or 1.5k

Olympic Distance athletes start at 8:00am. In the water start will depend on water temp and water level; this will be announced in your race email the week of the event. 

Sprint athletes start about 30 minutes later and as with all our events, the turn is marked with yellow triangle buoys.

Super Sprint athletes will start 45minutes later. You will swim to the first buoy, over 50m, and back.  

The swim course on Carlyle Lake is a simple out, over 50m, and back, U shaped course. Keep buoys on your right the entire way and you will exit the water under the swim structure, then up the swim chute to the transition area about 50m away. It is uphill on grass then carpet around to the back of the transition area. 

Lifeguards will be on ocean rescue boards, as well as waverunners. If you are in need of assistance, please wave your hand so water rescue personnel may assist. If you are not a strong swimmer, you are encouraged to not start at the front of the wave. To make the swim as enjoyable as possible, swim waves will be no larger than 100 athletes per wave. You will be issued a swim cap. Caps are absolutely mandatory. If you are allergic to latex, you must provide your own.  

Wetsuits have been used each year with the temps ranging between 75 and 66. We have a good inventory of wetsuits, Reserve by Tuesday at 3pm.

Swim Course Map

Bike: 10k, 20k or 23mi

Exiting the transition area, you will follow the bike chute lined with cones out past the parking, past the host hotel, then make a RIGHT turn past the boat launch. From that point, you will head out on the course. It is flat and in good condition, lined on both sides with farmland and very few houses. Just as you approach the state park, before the park entry, you will make a LEFT turn - NOT proceeding into the park.

Sprint athletes: From that point the Sprint turnaround is about 4 miles straight ahead, just before the intersection.

Olympic Distance athletes will continue a few more miles to a quick RIGHT. This is a narrow road and you will immediately see the hill up ahead. Following a fast and cautious downhill, you will have another LEFT turn monitored by officials. About a mile from this point, there is another RIGHT, following the road until the turnaround point at the party store.

Super Sprint athletes will proceed to the 5k mark and turnaround. Distance may be slightly different as we will choose a safe turnaround point. Your turnaround point will be marked with a Super Sprint Turnaround sign, arrows on the pavement and Support Crew. Please use caution when turning around. 

Every turn will be marked with both arrows on the pavement and chloroplast signs on the corners with officials. In addition, the 3 Disciplines truck will be leading, sweeping, and cruising the course. If you have mechanical problems, just wave the truck down and they will bring you back in. Remember this is an OPEN course, meaning you will be sharing the road with vehicles.

Because it is an OPEN course, please use caution at all times. It will be your responsibility to print maps and know the courses. It is the athlete’s responsibility to know and understand the courses. Helmets are a must. No helmet - no race. MP3 players on the bike course are an automatic disqualification. 

Due to the actions of a few athletes in past events, we are making you aware not only in this event, but ALL events, whether hosted by us or any other event management company, YOU MUST OBEY ALL OFFICIALS and EMERGENCY VEHICLES on the course AT ALL TIMES!! The bottom line here is that your race time is not more important than an EMERGENCY or OFFICIAL on the course. In the event of an emergency, you MUST obey official’s requests and you MUST STOP and pull off the road for any and all EMERGENCY VEHICLES to get through. This is not only to ensure that emergency vehicles can proceed, it is for your safety as well. Any athlete who does not adhere to this rule will be disqualified from this race and all 3D Discipline races for the rest of the year.

Bike Course Map

Run: 1mi, 6.2 mi or 3.1 mi

Exiting the transition area opposite the bike in/out end, you will follow the run chute out and down the drive, following the cones back up to a LEFT turn which takes you immediately onto the dam, then 1 mile to the other side with the beautiful Carlyle Lake on your left and the park on your right. This is a simple out and back run course. It’s flat like the bike with only ONE hill, which happens to be the only place where the course is covered in trees. That is a great spot for the sprint turnaround. 

Olympic Distance athletes will continue past this sprint turnaround to the turnaround at the 5000m point on the next dam.

Super Sprint athletes will proceed to the half mile marker on the dam. Your turnaround will be marked with an A-Frame Sign and support crew volunteer.

There will be 3 aid stations, one at each mile, which will be clearly marked along the course. You will follow small orange cones along with chalk and arrows on the course. Safety officials will be monitoring the course. If you need assistance, let them know.

Run Course Map


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.

Race Tips

We have had a lot of opportunities to train on this course, given the time of year of the event. The swim is relatively easy and straightforward. Rough water is rare. The bike course can get windy and if it’s a hot day, the wind gradually picks up as it heats up in the fields, so definitely take advantage when it is at your back. 

Olympic Distance athletes: don’t relax on the hill. This is a great spot to make a move. Those that have ridden the course a lot know that once you make your right turn, there is an immediate gradual incline you barely notice, so take advantage here and feel the burn to the top. You can make up a lot of ground doing that.

The run course totally depends on the day. If it is hot and humid, it can be a bakefest out there and you need to be prepared for that. 

He who watches the weather before this race has a good race. You can be having a PR day going into the run, and end up having one of your worst races, because, as beautiful as it is running across that dam, the sun reflecting off the water makes it much hotter out there. So if it is heating up on the bike start, we suggest you take in more water on the bike to prepare for the run. 

Hope that helps folks, see you out there!
