Rigby Lake Kids Rumble


July 8, 2023

Kids Triathlon

The RIGBY LAKE RUMBLE TRIATHLON will be held on Saturday, July 8th, 2023 at Jefferson County Lake in Rigby. In addition to there being both a SPRINT & OLYMPIC distance, we will also be having a KIDS Triathlon which will start as we get near the end of the SPRINT & OLYMPIC races.

The RIGBY LAKE RUMBLE TRIATHLON is usually our biggest triathlon of the year in Eastern Idaho! Come and Race with Tri Peaks Epic Events!


Course Description


The KIDS swim will be a simple swim right along the buoy’s near the entrance/exit on the south/west portion of the lake. There will be Jefferson County Search & Rescue personnel and multiple kayaks/paddleboards on the reservoir for safety.


The KIDS bike course will exit the lake through the parking lot and continue down Rigby Lake Road, turn right on Stockham Boulevard to 3950 East (Annis Highway), and then another right turn onto 400 North, back to Rigby Lake Road and return to the transition area.


The KIDS run will be one complete lap around Rigby Lake. We will have volunteers at all major road crossings as well as the entrance back into Rigby Lake. Please be nice to other people using the walking path. Run hard…there is a FINISHER MEDAL waiting for you after you pass the FINISH ARCH!
