Pewaukee (CBS 58)--Kids will get to expend a lot of their energy this weekend in a triathlon built around them. The event takes place Saturday morning at Pewaukee Lake. More than 300 children between 3 and 12 years old will swim, bike, and run. There are three different categories of age groups. Organizers say while competition is involved, it’s more about being active and having fun.

Unfortunately you can’t register for the Kids Triathlon.  It’s booked solid.  But spectators are welcome.  It runs from 7:30 until 10:30 in the morning.
