2019 Date TBD Sprint: Swim .5 miles Bike 15 miles Run 3 miles and Super Sprint: Swim .25 miles Bike 15 miles Run 3 miles and Kids Triathlon
Mark your calendars for the return of the Elton Eastside Triathlon in 2018! Lake Sammamish park and the Eastside are a prefect backdrop for a fun and fast triathlon. We have undergone some course changes so make sure you take a look at the course. The race has returned to its sprint-distance roots for a fast and furious course. And added a Super Sprint for those that would like a shorter swim. We'll also have a Kids Race this year for kids 5-10 years old.
Athletes can expect the same, energy-filled finish line experience, complete with a baked potato bar, awards celebration, and prize giveaways including a new bike!
Welcome Triathlon Teams & Clubs
We're excited to welcome the Seattle area triathlon teams and clubs to the race! They'll be out in force on race day.
