Below you will find our current course maps. These are subject to change at any time. The nature of extreme triathlons being done in extreme places is that course adjustments may need to be made (especially for inaugural events) due to unforeseen circumstances brought on by nature in these environments. We will do our best to adhere to these maps and no matter what we promise to put on the most challenging and beautiful course possible.

With a total gain of nearly 15,200’/4,630m between the bike/run courses and temps ranging from 85°F/29.5°C all the way down to a possible sub 40°F/4.5°C at the top of the bike course. Hawaii will surely challenge even those most seasoned athletes in the world.

Not yet active… The interactive points of interest and site map is a live Google Map that will be regularly updated as the event date nears. Once pulled up, simply scan the points of interest listed on the left side and as you scroll over each listed item the point will highlight itself on the map. You'll have to zoom in from there to see the desired area for more detail. Not every point is 100% set in stone, but it will provide a general overview of the race and associated activities. Any changes to the map will announced via email and on our social media sites. 


The course cutoffs will be strictly enforced by event officials. Any athlete not meeting any of the cutoffs will be disqualified from the event and marked as DNF (did not finish) on the official race results.

Race Management/Officials, Hawaii Police, and Medical reserve the right to pull any rider off the course at any time for any reason they deem necessary.


The swim course cutoff will be 2 hour and 20 minutes, 9:20am with a 7:00am scheduled start time. To meet the cutoff athletes must maintain a 3:37 per 100m pace. Athletes not meeting the cutoff will be pulled from the swim when the cutoff time elapses.


The bike course cutoff is 9 hours and 10 minutes after the swim cutoff, 6:30pm. If an athlete completes the swim and bike in exactly 11 hours and 30 minutes (swim cutoff plus bike cutoff), the must maintain a pace of 13.63mph (21.95kph). Athletes not meeting the cutoff will be pull from the event at the conclusion of the bike.

In addition to the course cutoff for the bike, we will have checkpoints that must be met along the bike course to ensure athletes are on pace to meet the final course cutoff. Athletes not meeting these course checkpoints may be pulled at the discretion of race officials, police, and medical crew.

  • 10:50am - To the Mile 22 Checkpoint (must hold 15mph average FLAT)
    On Saddle Road just after the turn onto Saddle Road. Also the first point at which support is allowed to start supporting.

  • 1:20pm - To the Mile 44.5 Checkpoint (must hold 9mph average ASCENT)
    On Saddle Road at the top of the first climb at the Mauna Kea Access Road.

  • Additional cutoffs will be added soon.


The run course cutoff is 8 hours after the bike cutoff, 2:30am. If an athlete completed the swim and bike in exactly 10 hours and 30 minutes they must maintain a pace of 16:50 minutes per mile (10:27 minutes per km). Athletes not meeting the cutoff will immediately by pulled from the run course.

In addition to the course cutoff for the run, we will have checkpoints that must be met along the run course to ensure athletes are on pace to meet the final course cutoff. Athletes not meeting these course checkpoints may be pulled at the discretion of race officials, police, and medical crew.

  • Additional cutoffs will be added soon.




Staff, medical, kayaks, rescue boats, and lifeguards will be present on the swim course and on the shore at all times during the swim and reserve the right to pull any competitor from the course, at any time, for any reason they deem necessary.

Aside from possible waves and/or current this should not be a difficult swim. It’s Hawaii, the water is clear, clean, salty, and warm. This is an open water ocean swim. Hapuna Beach is nestled in somewhat of a protected cove although in bad weather the waves do pickup. In December the waves are typically calm but you can never tell what might happen out there, it’s the Pacific Ocean. To keep swimmers closer to shore, given the location and nature of the swim, we will be instituting a 2 loop course. All swimmers will mass start running the white sand beach into the water (run part optional) and swim counterclockwise around the buoys. There will be 4 yellow corner buoys. The first 3 mark left turns. The last yellow buoy marks a right turn. The first 3 buoys are on the swimmer’s left with the last yellow buoy being on the swimmer’s right. We will have at least one centered smaller orange buoy on both of the long swim lengths as guidance buoys meant to help keep swimmers going straight. Once swimmers turn right at the last yellow buoy they will head to shore (inflatable and flags). Once exited the swimmers will run for a moment on the beach u-turning around a marked flag to head back out, the same way they started, for their second loop. The second loop is preformed the exact same way as the first.

When exiting the second time support team member(s) may run with their athlete to transition where one permitted support team member may enter transition to assist the athlete in preparation for the bike leg of the event. We will have restrooms and an unmanned hydration/nutrition table available. There are no changing tents so you can either change in the restrooms, behind a towel, under a swim parka, or get naked and get it done quick.

This event may or may not be wetsuit legal. If the water temp is found to be 78°F/28.5°C or under then wetsuits will be legal. We will not likely know this or make a judgement until race morning so we suggest bringing a suit just in case. If we do not allow wetsuits on race morning swim skins are always allowed. If we do allow wetsuits we suggest perhaps sleeveless, as full length wetsuits in warm water could easily cause overheating.




We cannot overstate how hard this bike is. Starting out of T2 at the Westin Hapuna Beach Resort is relatively flat on the Queen K. Once riders turn onto Waikoloa Rd things start to climb. From there it only gets more challenging. You start at sea level and begin climbing at about 9 miles. This climb (1 of 2) continues for the next 30+ miles. It’s a steady climb with grades ranging from 4-12% the entire time. At the course’s highest, riders will peak out at about 6,750’/2,060m of elevation (elevation, not total ascent). Keep in mind that in Dec, in Hawaii, at that elevation, the temperatures will no longer be the warm 75-85°F you started at and very well may have dropped to less than 40°F/4.5°C. The good news is after reaching that highest point of the bike, you descend, the bad news is that you’ll soon have to turnaround and ascend that decent. Your descend down the backside will be very fast and at times dangerous. It is a relatively straight road with very large shoulders and should be smooth as the entire road is brand new. This also means that riders tend to let the descent speed get away from them. Watch your speed and be responsible. Know that at around 55-miles is the u-turn and once turned around you immediately have to climb.

The u-turn will be marked and will have flaggers, however, it is on a decline and you will have to ride your brakes to be able to make it safely. Once cleared and turned around you follow the exact same path headed all the way back to transition at the resort. This course basically has two climbs, the first one, which is the longest at about 30+ miles and the second one on the return which is about 20-miles. Do not underestimate these. At the course’s highest point it will be cold and there’s the possibility of bad weather, even snow on rare occasions. For some people it may also mean labored breathing being at nearly 7,000’. But you are there briefly as you pass through. We recommend your support member(s) that are leapfrogging you in the support car (not following), have a variety of clothes and hydration/nutrition to account for heat, cold, and wet.

Also remember that this is an unsupported ride and all athletes must provide their own support member and vehicle that will stop at whatever mileage your team predetermines to handoff needed items. The shoulders and pullouts are big and at this time we are permitting teams to pull off anywhere on Saddle Road, miles 22-102 but not before our after that mileage. Be sure to note that USCSPC inspected/stickered helmets are required by our governing body (US inspected) and as a race we require every rider to have a solid white front light, blinking red back light, and neon reflective cycling vest on during the bike at all times. There are no exceptions to this. We also require each rider to carry his/her cell phone so that we can track them during the race. To see all mandatory items please click here.


It is each athlete's individual responsibility to get their bike to and from Alohaman™ in working and safe order and maintain/fix it while on the bike course. We will not transport or be responsible for bikes in any way, at any time. We will be inspecting each bike in the morning as they enter the Swim/Bike Transition (T1) and securing them until the swim cutoff at 9:20am (or whenever you claim it to start your ride). Beyond that your bike is in your hands, and the hands of your support crew. Upon entering the Swim/Bike Transition (T1), If your bike is deemed to be unsafe and cannot be easily fixed, you will not be able to event. We "may" have limited bike support onsite but do not count on it. We will do our best to get some onsite mechanics but the island all together is remote and we may not be able to secure them. Being XTri, athletes are ultimately responsible for their own bike and it’s mechanics.




The run course is all paved on road with a mixture of asphalt and concrete. There is a moderate climb out of transition for a couple miles in the beginning as well as some rolling ascent throughout the first 10-miles but nothing too difficult. For those that start their run before sunset know that there is very little shade. It will be hot and windy. Those starting their run after sunset have to worry less about the sun.

Runners will head north (running on the shoulder and AGAINST traffic) on the Queen K until they reach the u-turn point at about 14 miles. There will also be a manned hydration/nutrition station there. Runners then head south back the way they came veering right (crossing the intersection) just after mile 23 to head back towards the resort. Once turned and headed back runners will enjoy a tough but rapid descent back towards the finish line. Don’t be fooled by the descent though, there’s still some climbing left in the last 2-miles to earn the right to be called an Alohaman!

SUPPORT IS NOT A MANDATORY REQUIREMENT FOR THIS RUN (JUST FOR THE BIKE), however it is highly recommended. Please see the SUPPORT TEAM page for additional details and options for support runners.
