About the Event

Celebrate 20 years of community, fitness, and giving back at the Lake Wilderness Triathlon & Run Festival on Saturday, June 6, 2026, in scenic Maple Valley. This special anniversary edition offers something for everyone: choose a triathlon to swim, bike, and run your way to new friends, a duathlon if you'd rather skip the swim, or a running-only event to join the fun at your own pace. You can even form a custom relay team with friends or family, making it the perfect inclusive challenge at beautiful Lake Wilderness Park. The event is driven by a powerful community spirit, having donated thousands to Backpack Buddies and Seattle Children's Hospital and providing comfort to children through local police and fire departments. With a supportive, welcoming atmosphere ideal for first-timers and a scenic Pacific Northwest course that will delight seasoned athletes, this is more than a race—it's a local tradition that promotes health and directly enriches the community. Event rates increase on April 26 and May 24, so register early to secure your spot in this 20th-anniversary celebration. Whether you're chasing a personal best, starting a new fitness journey, or simply looking for a fun and meaningful way to spend a June morning, the Lake Wilderness Triathlon & Run Festival is your destination. Join the celebration and help make the next 20 years even better.
