Fox Lake Sprint Triathlon

Our Inaugural year (2017) was such a hit - we're back for more. Enjoy a swim in the Nippersink Lake, a ride through the gorgeous Chain O' Lakes State Park and a run down the community multi-use path in Fox Lake.

Time Trial swim start to keep everyone spread out during the lake swim. The bike has a few rollers and 2 quick turns throughout the 12.5 mile course. The run is very flat and fast with the majority of the run on a paved path. Athlete and spectator parking is close to transition.

Enjoy the music at the end of the race with food for all racers.
