The 2018 Trailblazer Tri was a blast!  Just check out this video taken by one participant of this crazy fun race that includes a 350-meter swim, 12.2 mile bike run, and 2.92-mile run around beautiful, historic Medical Lake!


This come-back race is growing like crazy, and is fun for both first timers and seasoned triathletes alike.  It’s a straight-shot swim, followed by a bike ride on paved roads, and ends with a scenic run around Medical Lake.  The race boasts a mass start with a single transition area–perfect for spectators.  Water and aid stations will be located at each transition, every 1-1.5 miles on the run, and at the finish line.

Thanks to everyone who participated in the 2017 event.  See results at:

Just wanted to say thanks for a fun event. Despite the weather, two of my sons and I had a great time. Really impressed with how well organized the event was, even though it was small. Hoping it grows in the coming years, we plan to return next year, and we’ll spread the word in our area (we live up in Boundary County, ID). In particular, I hope you’ll send our thanks to all the folks in kayaks watching over those of us who haven’t nailed the swim thing yet 🙂 That really gave us a lot of comfort and confidence to just get in the water and go for it. And please thank the folks who stood out in that miserable rain on the bike course to make sure we didn’t go off track. Looking forward to next year. These events wouldn’t exist without the volunteers who make them happen. We’re SO appreciative. Thanks so much!
