Lake Country Triathlon

Event Date: 
August 10, 2019
City Beach 304 W. Wisconsin Ave Oconomowoc, WI 53066

Started in 1983, the Lake Country Tri was one of the first and largest tris in Wisconsin. The race would sell out every year but eventually changed hands and disappeared in 1993. 

Silver Circle Sports Events, LLC brought the event back in 2015 and has sold out each year. In 2018, we have expanded the race to include a transition area twice the size, brought back free beer, finisher medals for all and expanded our new triathlete waves.
The course starts at Oconomowoc's City Beach with an sprint of olympic swim followed by a bike ride through Lake Country's beautiful countryside.  The run is right down Wisconsin Avenue with athletes and spectators cheering you on.

Wave Assignments -  NONE!

We are doing a time trial start.  Once the elite athletes have left, olympic distance will start from the beach every 3 seconds.  Sprint distance athletes will follow the same format once the olympic athletes have cleared a majority of the course.
Athletes should stage in the starting area based on where they feel comfortable starting. There will not be an assigned order.  

Endurance House Foundations Run and Triathlon programs are back for 2019 and bigger than ever!  If you're new to the sport or returning after a time away, then this is the best place to start back in the action!  The Foundations programs are specifically designed around the novice and beginner athlete and jam packed with information and coaching to get you to accomplishing your goals successfully.
