  Kids are filled with the energy to swim, bike, and run to the finish line. Coordinated in partnership with the School District's Physical Education teachers, 3rd through 8th graders compete in this noncontinuously timed event consisting of a 100m swim, a 3 mile bike ride, and a ½ mile run (7/8 graders will run 1 mile).

  While awards are given to the fastest in each division, the real winners are all the spirited students who bolt from the start and head towards every finish. Everyone receives a t-shirt and finisher medal. Park District athletic events are non-refundable. Registration deadline is September 20.
