Support is required for this event to assist the athlete in completing this epic adventure. Please make sure both you, the participant, and the REQUIRED support team read and understand this entire page.



We are offering four run course support options for athletes at the event. No matter which option you take for the run course, you are still REQUIRED to have a support captain and vehicle for the bike course.

Option one is HIGHLY RECOMMENDED due to the nature of the event.

OPTION 1 - HIGHLY RECOMMENDED. Participant has a support runner for the entire runner for the entire run course. This means the support runner will begin with the participant at the start of the run and must finish with them at the end of the run. Please see additional Option 1 rules in the Run Course Support section below.

OPTION 2 - Participant has two support runners. The first runner will begin the course with them. The second runner will meet them near the turnaround point on the run course. At the turnaround point, the first support runner will switch out with the second support runner. There is no transportation to and from the turnaround point so the second runner will have to drive the support vehicle to the turnaround point and the first support runner will have to drive the vehicle back to the finish line. If you are considering this option please make note of the Option 2 rules in the Run Course Support section below.

OPTION 3 - Participant hs one support runner meeting them at the turnaround point on the run. The participant will begin the run alone and will meet their support runner when they reach the turnaround point. Choosing this option means that the support runner must finish the run with the participant. There is no transportation to and from the turnaround point and there is no parking allowed at the turnaround point so you will have to have a driver take the support runner to the turnaround point, drop them off, and drive back to the finish line. If you are considering this option please make note of the Option 3 rules in the Run Course Support section below.

OPTION 4 - NOT RECOMMENDED. Participant can choose to not have a support runner at all and will start and finish the run course alone. If you choose this option please make note of the Option 4 rules in the Run Course Support section below.

We are able to now offer these three option because we were able to secure the medical coverage needed on the run course for us to feel that we were acting in the athlete’s best interest and ensure the best possible event experience for everyone.



We understand that support team member(s) are sometimes tough to find and possibly too expensive for some athletes to bring with them. If this is you, we encourage you to reach out to some of Iceland’s local triathlon, cycling, and running clubs/teams and possibly enlist their services. It is cheaper and easier to hire local athletes to be your support than travel with your own if that’s your struggle. Below you will find links to both emails of club/team leaders as well as links to social media groups you can directly post inquiries to in hopes of and securing your support.

Links coming soon…


Undoubtedly the fact each athlete has to supply their own support team of at least 1 but up to as many as 3 is a requirement that deters some folks from joining us. We understand that but we have 6 main reasons for requiring this and a number of them speak to the heart of what XTri is supposed to be.

  • NO HYDRATION/NUTRITION STATIONS ON THE BIKE AND LIMITED ON THE RUN (ABOUT EVERY 10K / VARIES PER EVENT) - Given the remote nature of XTri events it’s near impossible to put the amount of hydration/nutrition stations out that would be required as well as fully staff them. There just aren’t enough resources and manpower in most of these areas.

  • HELP TRACKING, MONITORING AND CARING FOR ATHLETES ON THE BIKE AND RUN - Given the remote nature of these events and the limited medical assets requiring each person to have a support team for the bike and run enables us to have an extra set of capable eyes on them at a higher frequency than the race alone is capable of. Especially on the run where the athlete is HIGHLY RECOMMENDED to have a support runner the entire time.

  • LIMITED PARKING & SHUTTLES - For 2 of our 3 XTris (Iceland and Hawaii) we HIGHLY RECOMMEND athletes to have a support runner complete the entire run course. For Alaska we allow support runners for the entire course but only require it for the mountain section (last 10-11 miles). This is for safety, hydration/nutrition support and fun, BUT it’s also because we do not have approved parking for up to 200+ cars at any other point on the course to meet and join them. Additionally there are simply not enough resources/shuttles, to transport support back to those cars after they finish, especially as late at night as so many cross the line.

  • SUPPORT MAKE GOOD MULES - On the bike the support car does the muling and your support team does the driving but on the run having your support runner by your side the entire time adds more fuel to your tank. Of course both the athlete and the support member(s) are required to have their own set of mandatory gear and hydration/nutrition, but having that support also means you can load them up with extra liquids and solids so that if yours run out before the next station, you are covered! They can be life savers, literally.

  • THE MORE THE MERRIER - The more support both physically and mentally that an athlete has during an event like this, the better. The course can be a lonely place and although that solitude is part of what makes XTri amazing, so is the comradely you feel sharing the experience with your support. In Iceland and Alaska you don’t really have to worry about the dark but on a course like Hawaii, a majority of runners will spend most of their time in the pitch black so having a support runner, if nothing else, helps with sanity in the abyss.

  • FUTURE XTRI FINISHERS - By having support on both the bike and the run we give that support person a look into the world of XTri. More often than not those support members either come back as support for others, join our XTri Staff, or better yet, become athletes themselves in the future. With such limited resources in these areas and XTri being a niche market, we need all the support and new athletes entering the ranks as possible to survive.


The  Ìsland Extreme Triathlon is one of hardest long distance 1-day triathlons on the planet. This unforgettable event will take athletes on a journey through the beautiful countryside of Iceland but does not come with some risk. 

Each registered athlete MUST have a Support Team Captain that is committed and capable of supporting the athlete throughout the day. Teams may consist of more than one support team member (as many as three) but should have one person designated as the Support Captain in charge of team management and fluent in English. 

As a support team member you must read and understand ALL of the Support Team Rules and Duties and abide by them for the entire event. Beyond safety and support, you support crew is part of the experience and add to the overall fun of the event. Support crews will undoubtedly have as much fun as the athletes, just in a different, yet essential way.  


The Support Captain job duties will include but are not limited to:

  • Driving the athlete

  • Carrying athlete bags

  • Getting needed items for the athlete

  • Attending schedule packet pickup with the athlete

  • Attending the mandatory pre-race briefing with the athlete

  • Assisting the athlete in transition before the race starts

  • Assisting the athlete out of the water

  • Assisting the athlete through T1 - Swim-to-Bike Transition (changing, getting warm, prepping for the bike, and getting to the bike mount line)

  • Identifying mileage and pull off areas along the bike course to be prepared to support the athlete with whatever they may need

  • Assisting the athlete through T2 - Bike-to-Run Transition (changing, getting warm, prepping for the run, and getting the athlete out onto the run course)

  • Clearing all athlete's gear from T2 and storing in vehicle. T2 is not a storage area.

  • Running and supporting the athlete as both athlete and at least one support team member complete the entire run course together.

  • Celebrating with the athlete at the end of this monumental day.

  • Providing support for the athlete after the race (specific nutrition needs, warmth, changing, etc.)

  • Ensuring the athlete is up in enough time to attend the awards brunch the day after the race

  • Ensuring the athlete is having the best experience possible throughout the day!

Support Team Rules

  • ENGLISH REQUIRED - The designated captain of the support team MUST speak and understand English so they can communicate with medical, officials, and event production teams if needed.

  • CAPTAIN REQUIRED - Each athlete must have a captain. This captain must be listed on the athlete's registration and must be present with the athlete at both the packet pickup and mandatory pre-race briefing. Athlete support teams may consist of anywhere from 1-3 members but no matter how many are on a team at least one must speak and understand English and be responsible for the management of the team.

  • OTHER SUPPORT MEMBERS - If a team has more than one support team member we would like to meet all members at packet pickup and the pre-race briefing but we realize that is not always possible. Any members beyond the captain that cannot make packet pickup may sign the support team form/waiver and give it to the athlete or captain to run for them in person as packet pickup.

  • SUPPORT FORMS & WAIVERS - All athletes and support team members (including the captain) must sign all necessary waivers at packet pickup and turn them in to be part of the support team. Support forms & waivers can be found on the PACKET PICKUP page.

  • ATHLETE WITHDRAWAL - If a support team's athlete withdraws from the event at any point before or during the event, a crew member is required to inform the event crew by texting the race crew (a phone number will be provided before the event). The event crew phone is manned from the pre-event meeting onwards. Please make sure to include the athlete's name and event number along with the withdraw notification.

  • SUPPORT TEAM VEHICLES & WINDSHIELD STICKERS - Only one support team vehicle is allowed per athlete no matter how many support team members you have. That support vehicle MUST have the small support vehicle sticker placed as shown on the sticker diagram (found on the PACKET PICKUP page). Any team members in the vehicle providing support MUST have completed the Support Team Forms/Waivers and have turned them in at packet pickup.

  • WHITE SUPPORT TEAM SHIRT - Each athlete will be given only one white support shirt at packet pickup, regardless of how many members are on the support team. If there is more than one member on a team, it is up to the athlete and captain to decide who gets what and when. We recommend ordering a shirt size that fits your biggest support team member so the shirt can be passed around if needed. During the race the support shirt must be worn for access to the following areas:

    • Transition (T1) pre-race to help with setup and to calm nerves.

    • Swim Exit to help athlete out of the water and get them to transition. The athlete will be cold and they will need your help to get to transition.

    • Transition (T1) swim-to-bike to help athlete warmup, change, and prep for bike. This could be quick or it could take a while. Be prepared to do what it takes to warm them up and change them, they will not be as capable as they think.

    • Transition (T2) bike-to-run to help athlete change, and prep for the run. Support also is responsible for clearing all athlete belongings out of T2 immediately and putting them in the support car. T2 is temporary for changing and transition not for storage of any kind.

  • WHITE SUPPORT WRISTBAND - Each athlete will be given only one white support wristband at packet pickup, regardless of how many members are on their support team. We will not put the wristband on anyone at packet pickup because once we put it on it is permanently on them until it's cutoff. THE WRISTBAND IS ONLY FOR THE MAIN SUPPORTING RUNNER.


Support vehicles/members are to drop off their athletes at the swim start on the southwest side of the cove for the swim start. There is no parking for this. There will be a continuously moving line that will come in, drop the athlete, u-turn, and head back out. This should move quick and we recommend car pooling if possible. We do not really care who or how the athlete gets to the swim start. You can carpool with another athlete or have a non support vehicle drop you off, whatever you want, just get to the swim start. You cannot walk, run, or swim there. The road and waters are too dangerous/far that early in the morning when it’s not light out and without adequate shoulder.

Once athletes are dropped off support vehicles will make their way down the highway to the swim exit/T1 exit. Please refer to the course maps page and the interactive site map for exact parking location(s) at the swim exit. Once parked support team member(s) are to head to the T1 area and setup their athlete’s gear. This is NOT to be done with the athlete prior to dropping them off. This is ONLY to be done by the support team after the athlete is dropped at swim start. One support team member will be allowed into T1 (show the shirt) to setup their athlete’s area. Since the athlete will not be present to assist with this we suggest a high level of discuss on a trial setup run-through prior to the event to make sure athlete is happy with how their support plans on setting up T1. Once the swim starts we will ask all support members to exit transition and make their way to the swim exit to help their athlete out and through T2.

While only one support member (with shirt) is allowed in and out of T1 both before and during the event, all support members (if more than one) are allowed to wait at the swim exit and assist their swimmer out of the water and towards transition. Swimmers will undoubtedly be cold and possibly have some feet/leg numbness going on. Support will likely be needed to help them get their legs under them and warmup. Support (with shirt) is then allowed to help athlete into transition and ultimately onto the bike. As support, be prepared to guide your athlete to their designated spot, help dry them, warm them, change them, and get them on their way. Athletes should NOT attempt to start the ride if they are shivering uncontrollably OR cannot talk without shaking/stuttering. This isn’t overly common but to be clear, we want to make sure each athlete is in complete control of their body before they attempt to operate their bike. Athletes may take as long as they would like in T1 before starting the bike but your time is ticking away as you sit. There will be an unmanned station with water, energy drink, and energy gels available in transition as well as restrooms. There will not be changing tent. There is no one around besides the event support, athletes, and production team. No one cares about anyone else’s nakedness. If you still don’t want to openly change you may do a deck change under a chest/waist wrapped towel or have your support hold a towel up while you change behind it. Some people also put long swim parkas on to warm up and easily change under those. Support and their athlete then exit transition with athlete helmet and shoes on and bike in hand.


Once the athlete and support exit transition they both safely cross the road before mountain the bike. Once on the other side support must stand on the shoulder outside the white line and help their athlete get on the bike and get going. Support should keep in mind not only their mounting athlete but traffic that may be coming from behind. Each athlete is required to have a high visibility reflective vest and both front and back lights but cars may still not see the athletes in this venerable spot as they start the bike. Everyone needs to show extra caution and awareness. PLEASE BE AWARE that as we approach the event we may change this to just the athletes crossing the road and mounting in order to reduce the people around the road.

Once the rider is on his/her way support returns to transition and gathers all their athlete’s swim gear that was left behind. That gear is to be taken with the support team vehicle when it leaves. No one will return to T1 after they leave. Once on the road the support team vehicle (provided stickers on front and back windshield) must always be heading the direction the riders are heading, counterclockwise around the Peninsula.

NO VEHICLE may follow their rider, ever! Any rider that you come up on (yours or not) must be passed when it is safe to do so. Again, do not ride behind or alongside any riders at any time. Before the event we recommend that all support teams and their athletes plan out the multiple support stop areas and the acceptable mileage ranges to stop and offer aid. Be flexible. Remember you can only stop outside the white line and only when it’s a safe area to do so. This may mean that your desired mileage for a stop is either already full of cars, doesn’t have enough room on the shoulder, or the shoulder is too steep to safely do so. You can plan this out better by driving the course ahead of time and/or being sure to identify as big of a range as possible to expect a stop (ie first stop somewhere between 40k-45k/25-28m). Riders “should” be able to carry enough hydration and nutrition to last the first AND last 40k-50k/25-31m or 90-120-minutes limiting stops to only what’s necessary and avoiding any traffic hazards or accidents.

Please keep in mind that there is potential for extremely high wind and moderate coldness. This may change your support distance plans. It may also change your clothing and hydration/nutrition plans. Plan for the worst and hope for the best. Be able to roll with the punches, make changes, and problem solve on the fly without getting discouraged and frazzled. Keep your calm and realize the goal is the finish line. Do what you have to to get there while staying safe and having fun.

Once the support and athlete have met for the last time support vehicles are to head to the T2 area. Parking for the T2 area will be detailed on the site map shown on the course maps page. We would recommend making sure the last planned bike support stop leaves more than enough time for support to park and make it to T2 while carrying all their athlete’s run gear a distance of anywhere from 1/4k-1k or 1/10-1/4m. Plan ahead.


We allow one support team member (wearing the white support shirt) to help their athlete off the bike (if needed) and through T2. T2 is a temporary area and extremely small. It’s not like T1 where all bikes are setup. T2 is big enough for 4-5 athletes at once to put their bike, change, and be on their way with their support clearing out all their stuff. Nothing is to be left in T2 for more than 5-10min after an athlete leaves. If a support team only consists of one support person and that person may also the support runner, then after the athlete is changed and ready to run, both the athlete and their one support member, must go to the support car and pack it up before the go out on the run. If a support team has more than one member we recommend the other non running member helps the athlete through T2 and cleans up after. Then while that member is doing that the support runner can go with the athlete without delay.

Remember that we HIGHLY RECOMMEND one support runner to accompany each athlete on the entire run course.


Whomever starts to run with the athlete MUST do the entire run start to finish. If an athlete’s support runner cannot make the distance, both their days are done. The only exception would be if the athlete makes sure the support runner is ok and taken care of (ie medical, volunteers, support staff). This is only meant for extreme situations where it’s necessary to complete the event because your support runner cannot continue. Please also note that it is not the responsibility of any other team to let someone join their team and if they’re nice enough to do so they do not have to accommodate your pace. Be sure to pick a team you can keep up with and if they are slower than you you have to slow to meet their pace. Anyone caught far beyond their support will be disqualified immediately. This is to ensure we have accountability for everyone on the run course.

Athletes and support runners MUST carry a set of their own mandatory equipment at all times. Additionally support runners are often times referred to as “mules” meaning that they double up carrying not only their own supplies but also extra supplies for their runner.


If you choose the option to have two support runners, there is absolutely NO PARKING allowed at the turnaround point. Second support runners will need to get out of the car and make the switch immediately when then first support runner and participant arrive at the turnaround point. NO SUPPORT VEHICLES ARE ALLOWED TO DRIVE THE MOUNTAIN ROAD. The road should remain as clear as possible for participants, support, and race/medical crew. Support vehicles will need to get to and from the turnaround point via the main road the travels around the mountain.


If you choose the option to have one support runner meeting you at the turnaround point, there is absolutely NO PARKING allowed at the turnaround point. And there is no transportation provided by the event to and from the turnaround point. Second support runners will need to be driven to the turnaround point in the support vehicle and dropped off. NO SUPPORT VEHICLES ARE ALLOWED TO DRIVE THE MOUNTAIN ROAD. The road should remain as clear as possible for participants, support, and race/medical crew. Support vehicles will need to get to and from the turnaround point via the main road the travels around the mountain.


This option is NOT RECOMMENDED due to the nature of the event. Those without a support runner are required to carry an appropriate amount of nutrition and hydration to travel from hydration/nutrition station to hydration/nutrition station, see course page for details about where hydration/nutrition stations will be.


The athlete will receive a finisher’s shirt for finishing, the support will not. Support is there to support the athlete in reaching this monumental goal. Both the event and the athletes immensely appreciate the support teams/members but the shirt is for the athletes and athletes alone. Thank you for your understanding.

At the end of the event it is also the support team’s job to assist the athlete in whatever they may need. They will likely be exhausted and may need medical attention. They will at the very least need to sit, rest, and will need some food and drink. Please assist them in getting these things accomplished as well as providing this for yourselves. If we can also be of assistance please let us know.

Going into the next day we welcome athletes, support, volunteers, race crew, and spectators to our finisher’s brunch. Support, please help make sure your athlete is awake and on-time to this fun occasion. We will eat, talk, hand out finisher’s shirts, awards to the top 3 male and female overalls, and take a group finisher’s photo.
