Course description
Distances for the primary courses are:
- SWIM: 750 meters (lake)
- BIKE: 16 miles
- RUN: 5 kilometers
The swim is one clockwise 750 meter loop in the lake. Wetsuits are legal and water temperatures are expected in the low 70s. Depending on wind, swimmers may encounter light to moderate chop and a small current.
The bike is a single 16 mile loop on rural roads. Road surfaces are generally good with a few rough spots. The course has five turns marked with pavement arrows and directional signs. Police and volunteers staff the main intersections.
The run is a one-loop 5k with several out-and-back spurs. The run course is relatively flat and shaded and allows athletes to see other competitors at multiple points. Visit the organization's website for the most recent information.
