The Eagle River Triathlon is sprint distance triathlon on a stunning course in Chugiak, Alaska just 20 miles north of Anchorage. Known for its spectacular views, and fun, yet challenging bike course, the Eagle River Tri course is a favorite among racers in Alaska. 


SWIM – 300 yards

The swim takes place in the Chugiak High School swimming pool.
To help with distancing and general covid mitigation,
the 2021 swim will be a 300 yard snake swim.
There will be no pre-swim warm up available this year. 

What is a snake swim? (click on image for full-size diagram)

Swimmers will enter the water in the left/north end of the pool
starting with lane #6. Racers will swim the length of the lane,
turn at the wall and then swim back down the same lane on the other side - completing a full lap (50 yards). With the first lap complete racers will then swim under the lane line, entering lane #5 and then proceed in the same manner as lap one. They will continue snaking up and down the lanes until completing the 300-yard/12 lengths/6-lane snake swim. Upon completion of the swim
, racers exit the pool and out the door designated for racers only located at the exit of lane #1 and into the parking lot to the transition area to prepare for the bike leg of the race. 


Key swim details:

  • All racers must enter the pool through the inside entrance of the school (also designated as the pool entrance). Entrance to the pool is at the far northeast end of the school.

  • Timing chips will be passed out on the pool deck along with plastic ankle straps for the chip. If you have your own strap feel free to bring it. Place the strap on you left ankle (before you start your swim) and do not take it off until you cross the finish line. These are not disposable chips and must be left off at the finish line and placed in the chip bucket. 

  • In a snake swim there will be other swimmers in the lane ahead of and behind you; it's your responsibility to stay on your designated side of the lane.

  • Racers will not be allowed to put any gear (i.e. bike helmet, race belt/bib, etc) on the pool deck. All gear must be left in the racer's transition area.

  • All racers are required to wear a mask from the time they enter the school until they enter the pool to start their swim.

    • Disposable masks are recommended.

    • When getting in the pool there will be a bucket to dispose masks in.

    • Racers will not be required to have a mask on upon exiting the pool and entering the transition area.  

    • Racers should have their own additional mask(s) in the transition area for use before and after their event.

BIKE – 12.4 miles

The bike course consists of two out-and-back sections. Bikers exit out of the north end of the transition area and turn left (west) out of the transition area and up a short ramp to take a sharp right (north) onto S Birchwood Loop Road. Racers continue to the first turnaround at the corner of Old Cranberry Drive & K-L Lane. There will be a cone and volunteer marking the turnaround. Returning back on this same stretch of road, bikers go past Chugiak High School and turn right onto Hillcrest Drive, directly across from the south entrance into Chugiak HS. Racers will then continue through this second out-and-back section of the course which winds through various streets. Following the signs and volunteers, racers then turn at the second turnaround located at North Eagle River Road and ride this same stretch of the course back to the high school. Upon returning to the school, cyclists will cross S Birchwood Loop Road and enter the school grounds through the south entrance and follow flagging to the right back into transition area to change to run.
 This is a hot corner (that's tri lingo for "very busy") so please cross with care. Racers must slow down entering the high school and down the final stretch to the transition area.


Key bike details:

  • Bike drop off begins race morning at 6:00 a.m. There is no drop off prior to that time or the day before.

Racers will use the same transition area for both T1 (from swim to bike) and T2 (from bike to run). All racers will have an assigned slot in the transition area.


  • Transition slots for the top 30 and teams are numbered according to bib numbers. Racer (or team) has an assigned slot.

  • T1 and T2 are the same “active” transition areas. 

  • Transition set-up/bike drop-off begins race morning at 8:00 a.m. Don’t worry, you do not need to arrive at 8:00 a.m., racers may set up any time prior to their start time (even after the race has begun).

  • All racers are required to wear a mask at any time they are not actively racing. This means anywhere in the venue indoors and outdoors and in the transition area when not racing. 

    • Disposable masks are recommended.

    • Racers should have their own additional mask(s) in the transition area for use before and after their event.

    • All masks must be disposed of in a trash or other designated receptacle. 

  • Please stay alert at all times while in the transition area as it will be active with racers coming in and out. Once you complete your race, please use the designated exits for removing gear to prevent accidents with active racers in transition. 

  • Only racers are allowed in the transition area. 

  • You are responsible for providing your own bike stand for your transition slot. Stay within your own space and do not intrude on others space.

  • You must use a bike stand. Kickstands are not allowed in transition, they are not reliable and can cause other bikes to fall (think dominoes). 

  • Bikes are NOT allowed to be laid down or positioned upside down.

  • Solo racers must return their bike to their designated slot before starting the run. 

  • Please do not loiter in the transition area. Racers are only permitted in the area while setting-up or removing their gear, or while racing. 

  • Once your race is complete we ask that you remove your items as soon as possible and return them to your vehicle to minimize the number of racers in the transition area. Racers are asked to depart the event as soon as reasonably possible following the completion of their race (this was part of our mitigation plan.)

USAT Rules & Sanctioning


This is a USA Triathlon (USAT) sanctioned event. All USAT rules apply. Participation in a USAT sanctioned event means the event director has the proper permits in place, liability and athlete excess medical insurance coverage and the event plan has met the standard of organization required. USA Triathlon provides rules, guidance and governance to set the standard for safe and fair multi-sport races. 


For more information on USA Triathlon, race rules, and FAQs visit the USAT website at


It is every racer’s responsibility to know the rules, but we like to point out some key USAT rules and other things to remember:

  • No transferring bib numbers to another participant.

  • Drafting on the bike is not permitted. Keep at least three bike lengths of clear space between you and the cyclist in front. If you move into the zone, you must pass within 15 seconds. 

  • Adult participants (13 and over) shall not accept assistance of any kind (such as food, drink, equipment, pacing or bike handling) from any person except a race official. 

  • Adult participants must display their race number at all times. Racers are responsible for making sure the timers are aware of their number. Solo racers have different colored numbers than teams.

  • All personal equipment and belongings taken out onto the course must stay on the athlete the entire time

  • It is your responsibility to know the course and transition areas.

Other Important Race Information

  • Due to Covid there will be no spectators allowed at the 2021 event. Please leave dogs and other pets at home (please tell your family and friends).

  • Label all of your gear with your name and/or race number.

  • Follow all directions of race officials, traffic control personnel, and volunteers.



All teams will have their bike slot inside the transition area (southeast corner). All tag-offs will be done at the team bike slot. All team members must follow the same swim, bike, and run rules as outlined for adult individual racers.

Read through the Swim, Bike, Run and Transition information above as most of those items pertain to teams too.


Additional team information:​

  • Team swimmers should be on deck at 9:00 a.m.

  • Swimmers pick up their timing chip on the pool deck.

  • Team swimmers will start immediately after the top 30 seeded individuals and possibly a few additional racers. The volunteer passing out timing chips on the pool deck will alert you as to which individual bib number the first team will follow. All other team swimmers will follow in bib order.

  • If one team member does two events (i.e. swim and bike, run and bike, etc.), the racer must follow all the transition rules as if you were a solo-event team member (i.e. use your team slot in the transition for your bike and gear).

  • Swimmers must leave swim and proceed to their slot in T1 to tag off to their biker at their biker's transition slot. Tag-offs are not permitted on the sidewalk outside of T1. 

  • The swimmer transfers their timing chip to the biker by taking the ankle strap (with the chip) off and giving it to the biker to put it on their ankle. 

  • After completing the bike leg, the biker tags off to the runner by taking the ankle strap (with the chip) off and giving it to the runner to put it on their ankle. 

  • The timing chips are not disposable chips and must be left at the finish line and placed in the chip bucket.

  • Good luck and have fun!


Event parking is in the main Chugiak High School parking lot and at Birchwood Elementary School. 


Please follow all directions of traffic control personnel, volunteers, APD, and signs. Under no circumstances can cars pull off on the side of S. Birchwood Loop Road, or other neighboring roads, to drop racers. All racers and vehicles must use the designated parking areas.

  • West Parking Lot (main parking lot) From South Birchwood Loop Road, access the west lot by entering through the 2nd entrance to Chugiak High School. This entrance is usually an exit only for vehicles, but on race day is used for parking access in and out of the school. This entrance will share the "bike out" lane coming from the transition area. The driveway will be flagged to separate bikers and vehicles. All vehicle traffic will be one-way alternating in and out. There will be traffic control flaggers at both the top and the bottom of this entrance controlling incoming and exiting vehicles. Follow all directions from traffic control personnel. Parking lot is open all day but arriving and departing may be slow. Please be patient! 

    • The West Parking Lot is expected to fill up; when it does fill up follow the signs past the Chugiak High School entrance and continue approximately 1 mile and take a right on Birchtree Street. Birchwood Elementary School is on the right at the end of the road. Overflow parking is in the elementary school lot. It is an easy walk on a grass pathway between Birchwood Elementary School and Chugiak High School.

    • The East Parking Lot (back lot) is closed completely to all vehicles all day.

  • Birchwood Elementary School
    Both the upper lot and lower lot are available for parking on race day.




The event is timed by Skinny Raven Events and Timing. There will be a timing device operated by timing personnel at each racer’s swim start. Timing mats throughout the race course will capture racer’s times at the following locations.

  • Door exiting the pool to the outside: This marks the end of the swim and start of the T1 split. 

  • Bike out: This marks the end of the Transition 1 split and the beginning of the bike split.

  • Bike in: Racers will dismount their bike at the conclusion of the bike and run over the same mat they did for their “bike out” to capture the end of the bike split and beginning of the T2 split.

  • Run out: This marks the end of the Transition 2 split and the start of the run split.

  • Finish line: Captures the end of the run split and overall race time.


In the event you lose your timing chip once your race has started, please continue with your race. While there is no guarantee we will be able to capture all split times, we will be able to get accurate start and finish times. 



  • Due to Covid there are no spectators allowed at the 2021 event. 



Official race bib transfer policy: No participant may transfer his/her entry slot/bib number to another individual. If an individual is found to have raced under someone else's name or bib number, that person, and the originally assigned racer will be disqualified and risk being banned from future Eagle River Triathlon events. 


Name changes will be available for Teams at a charge of $10.00/person/change. All changes must be done no later than June 3, 2021. There will be no name changes made on race day.
