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.

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.

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.

  • All participants must wear an undamaged and unaltered helmet, which meets or exceeds the safety standards of the Consumer Product Safety Commission (CPSC), and which is clearly labeled by the manufacturer as satisfying such standards.

  • The chin-strap must be fastened at all times.

  • You are responsible for knowing the bike course. Any potentially confusing intersections will be marked with traffic cones and signage.

  • Stay as far to the right as possible and practical. The bike course takes place on an open road.

  • No drafting. You must stay at least 7 meters (or 3 bike lengths) behind the bike in front of you.

RUN – 3.1 miles

The run is a single out-and-back course. Runners exit the south entrance of the parking lot and head east towards the Glenn Highway on the bike path. Proceeding through the underpass, runners then turn left (north) onto the paved trail adjacent to the highway. Runners will continue on the paved trail to the turnaround and then head back on the same route to the finish line. 

  • Obey all directions of volunteers and traffic officials. 

  • You are responsible for knowing the run course. Any potentially confusing intersections will be marked with traffic cones and signage.

  • Wear your bib in the front. Make sure your bib number is visible to the front when you cross the finish line. 

  • There is a water station at the run turnaround and finish line. 

  • There are no restrooms on the run course.

  • The timing chips are not disposable chips and must be left at the finish line and placed in the chip bucket. A volunteer will assist you in taking your timing chip off.

  • Once you complete your race you must exit the finish corral as quickly as possible. Masks be put on upon completion of the event. Disposable masks will be available to racers in the finish corral.   

View Run Course Map


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).

  • 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.)

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.

  • Helmets must be worn at all times while on your bike. This means before, during, and after the event (including when transporting bike to and from your vehicle.). Chinstraps must be fastened while on your bike.

  • All bicycle bar ends must be solidly plugged.

  • 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.

We welcome spectators at the event. Please leave your dog friends at home. We know they are great cheerleaders, but a loose dog can quickly turn a racer's day south. 


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.
