It is essential that every athlete read and fully understand the event’s expectations, rules, and risks. Please thoroughly review this entire website before registering.

We allocate 250 total spots to each event. 230 are general entry, first-come-first-serve. The remaining 20 are divided equally between the pros and race director’s choice. Pros can email their license to us for their discount code via the pro section below. Race director’s choice entries are only available if we have sold out.


Save $100-$150 per event registration when you register for multiple E3 events (Alaska, Iceland, Alohaman) in the same calendar year, click the button below for details.

Pro Entries

Pro triathlete’s receive a 50% discount. If you are a pro and would like to take advantage of this discount please email us a copy of your pro license issued by your country’s triathlon governing body. We only have 10 pro spots available to each event.



E3 does not offer refunds or transfers to other athletes for any reason. HOWEVER, for those US Citizens wanting to be eligible for monetary refunds… a third-party registration insurance option is available during time of registration if you purchase it. The coverage is comprehensive but does not cover everything. Claims are filed through Allianz, not the event.


We do allow event-to-event transfers within the same calendar year. For details about the transfer policy and how to transfer your entry click the button below.


We will not mail packets before or after the event. You must get your packet in-person at packet pickup. You will receive the following items included in your registration:

  • Event Entry

  • Swim Cap

  • Athlete Numbers, stickers, and wristband

  • Support Crew Shirt (Alaska Only) and wristband

  • GPS tracking via athlete’s phone


The color of that shirt (orange or white) depends on beating the run course mile 23 cutoff at 9pm. All those that make it to mile 23 at or before 9pm that day will be permitted to make the second climb up Mt. Alyeska to attempt to get the orange shirt. Anyone that reaches mile 23 after 9pm will be directed to the “Low Route.” Both routes are the same distance and have the same finish line cutoff of 11:00pm we just have to make sure that the finisher’s past 9pm stay lower due to late night safety on the mountain.

PLEASE NOTE that Alyeska Mountain Patrol will be all over both sides of the mountain all day. They reserve the right to pull anyone from the course at any time. Typically they do so if athletes are caught between checking/cutoff points and are going to slow to make it. Other reasons include but are not limited to medical, weather, wildlife, etc.

To review all courses and all cutoffs for the courses, including even more details on High Route and Low Route run courses, please visit the course webpage.
