We are happy to bring back the Crystal Lake Aquathon for the 9th year! This annual event will be returning to the ideal confines of Three Oaks Recreational Center in Crystal Lake, IL. As the original Illinois Aquathon, this race will offer 4 timed options. All proceeds from the race benefit Girls on the Run of Northwest Illinois!

Timed Races

- Sprint Distance (500m swim, 5k run)

- Olympic Distance (1 mile swim, 10k run)

- 2 Mile Swim
-1 Mile Swim. Please note the 1-mile swim does not include awards but is timed.

The swim portion takes place in a modified quarry (swim around 3 islands!), and the run is on a combination of trail, sand, and pavement. Wet suits will be allowed if it is below 78 degrees (decision to be made by City of Crystal Lake staff based on water temperature).

Kids' Race

The Kids' Race is perfect for anyone ages 7-12 that would like to try the Aquathon but needs a shorter distance. It includes a 100m swim and a 1 mile run. Swag is included, along with a swim cap. All Kids' Race participants will receive a finisher's medal however there are no awards. Lifeguards and a swim angel will be in the water with the swimmers for safety and encouragement. There is a relay option, so if your child wants to partner with a friend, it's a great way for them to compete together!

Adaptive Race

The Adaptive Race will be a one mile swim only. Swimmers will be allowed physical support from their own family/friends only for protection of the racers and volunteers and may use adaptive equipment in the water as needed.
