BODY MARKING & SWIM CAPS

After checking in, please proceed to the body marking area. Your race number will be marked on your leg and arm. These markings help officials identify you at the start and finish of the swim, as well as during the bike portion of your race.

Race Day Events provides all participants with latex swim caps, with colors indicating your assigned wave. If you have a latex allergy, we encourage you to bring your own swim cap. It does not need to match your wave color, though it is appreciated if it does. If your cap is a different color, please notify a race official of your latex allergy before your wave enters the water.

WETSUITS

Wetsuits are mandatory in water temperatures less than 58º F.

Competitors may wear wetsuits if the water temperature is 78 degrees or lower. 

If the water temperature is between 78.1 – 83.9 degrees, competitors may wear wetsuits but will not be eligible for awards (if this happens, a special start wave will be created).

Wetsuits are prohibited in water temperatures greater than 84º F.

 Wetsuits cannot measure more than 5mm thick.

It is strongly encouraged to practice open water swimming prior to the event – with and without a wetsuit.

SERIES & SCORING

The Lake Mills Triathlon is race number one of seven in the Wisconsin Tri Series!

All races in the series offer sprint distance while the Wisconsin Triterium, Green Lake, and Tri-ing For A Cure Triathlons also offer an Olympic distance.

Compete in as many races as you can for a chance at winning both overall and division awards for the Wisconsin Tri Series!

Series scoring is based on your five best times out of the seven races.
