Course details and categories

  • 5k run

Kids course options:

  • Short course: 1 lap swim, <2 mile bike, <1 mile run
  • Long course: 2 lap swim, <2 mile bike, <1 mile run

Kids may start their swim on a water slide; the recorded triathlon time begins when the participant hits the water at the bottom of the slide. The kids bike course is mostly gravel. The kids run follows last year’s course in reverse, using the Illiamna Loop on the NPRSA trails, so the final section is downhill rather than uphill.
