Course Description


The SWIM portion of the RIGBY LAKE RUMBLE TRIATHLON will begin on the west side of the lake, heading direct east, then head back west to another buoy on the north and then back directly south just west of the slide. The SPRINT racers will do 1 lap, and OLYMPIC racers will do 2.  The KIDS 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 BIKE section of the RIGBY LAKE RUMBLE TRIATHLON will be a mostly flat course for both the Sprint, Olympic & Kids races.  The SPRINT  & OLYMPIC course will begin with exiting through the parking lot of the lake (avoiding speed bumps!) onto Rigby Lake Road. It will continue down to 400 North and turn RIGHT just past Westmark Credit Union, onto Stockham Boulevard, then another RIGHT onto 3950 North (Annis Highway). Racers will continue until you have a LEFT turn onto 700 East (Menan/Lorenzo Highway). You will continue down to the base of the Annis Butte Cemetery for the SPRINT TURNAROUND. Sprint racers will follow this same path back to Jefferson County Lake. The OLYMPIC course continue over the Butte until they hit 3600 East and turn RIGHT and continue North towards the Menan Buttes. The turnaround point will be just past the East Butte Road, and then return on the same path back to Jefferson County Lake. There will be volunteers and police at all major intersections—Use CAUTION on all corners and watch for gravel, cattle, and random farm sprinklers! There will be a minor AID STATION that will have bottles of water only on the OLYMPIC course, nothing on the SPRINT course.  You will be coached on where to dismount your bike and get ready for your run. 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 North (Annis Highway), and then another right turn onto 400 North, back to Rigby Lake Road and return to the transition area.


The RUN portion of the RIGBY LAKE RUMBLE TRIATHLON will begin from the bike transition area and make almost 1 loop around Rigby Lake to the main entrance/exit. Runners will continue down Rigby Lake Road. The SPRINT RUNNERS will turn around just in front of Point S. The OLYPMIC RUNNERS will continue past this point and turn right onto Stockham Boulevard and then another right onto 3950 North. Olympic runners will continue to the turnaround point at Junkhouse Road. There will be an additional aid station at this turn around. Please hydrate well racers! 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!
