MEDICAL LAKE – It's the silver anniversary for the Trailblazers Triathlon at Medical Lake. Dave Perry, who began the event 25 years ago to raise funds for adult athletic teams, and who's still in charge, recalls its inception. "We weren't sure what to do," Perry said. "One year we did a bed race. But that was more just for fun. Then we started thinking about what we can do. We have the water here, so we thought, 'What about a bathtub race, or make your own boat out of milk cartons?' Then sitting around watching TV one night, the Hawaiian Iron Man came on, and it just struck me, 'There it is.' We have the water, we have the path."
