Youth Marathon

We will have a check-in/registration booth at the entrance to Rexburg Rapids. Please bring your child/ren in their swimsuits and ready to go to save on time and hassle.

Please show up early so you have time to drop your child’s bike and transition bag off in the transition area (orange box on map).

We will have shirts for the Youth Triathlon at check in, parents please grab those so your children aren’t trying to pack them around everywhere.

-Kid’s Race Series Participants can pick up their medals for those who have completed 3 of the 4 races!


Kids can use life jackets for the swim, there will be some available at the pool but sizing is limited.

NO INFLATABLE wings, arm floaties or floatation devices; REAL LIFEJACKETS only. Participants are NOT required to wear a life jacket, but if they are not a strong swimmer then it is suggested they use one.

Bike Transition 

After they swim their laps they will go out the North East gate of the pool and get their bikes in the transfer section. Some suggested items to have in their bag at the transition area: towel to dry off, shoes and socks to wear for the bike and run, dry shirt and shorts to throw on over swimsuits, or not, child’s choice. HELMETS REQUIRED for biking portion of the race. No helmet, no race.

Passing-TELL YOUR CHILDREN that when passing during the biking section to make sure the path is clear and there is space to safely pass, if there is not then they need to wait until there is, this isn’t a timed race, so there is not enough rush to risk injury.

*NO earphones or music devices are allowed to be worn or used during the race. Participants please leave all valuables and electronics in your car, or with a parent, so they are not lost, stolen, or broken during the race.



The course will be marked with cones and tape, and there will be volunteers at crucial spots and turn arounds to direct the children. Parents please stay off the course, unless you are a course volunteer and have been assigned to a spot. The bike paths will be full of kids biking and it may get tricky with bikers or runners trying to avoid running you over or getting confused about who is a parent and who is a volunteer.

Run Transition 

Transition to run will be after they’ve biked along the bike path and behind fat cats (intermediate bikers only), they will come back across the west bridge and transition to a run-which starts by going across the middle bridge and around the north fields (intermediate 2 laps, beginners 1 lap), then coming back across the middle bridge to finish the race.

Finish Line

The Finish Line will be in the parking lot by the bike transition area on the north east side of the pool.

We will have Youth Triathlon Medals at the finish line to put on the participant as they cross the line!


Seeing as our race will cross the Rexburg Rapids parking lot, all parking lots will be closed except for the large main one north of the fields, please enter from the North East entrance on N 1st E.
