Welcome to the big stage.

The Lake Meridian Triathlon is the crown jewel of the Pacific Northwest and the undisputed flagship of the RTB season. This is where the energy is highest, the crowds are loudest, and the competition is at its peak. Whether you’re taking on the endurance test of the Olympic, the high-speed Sprint, or the explosive Super Sprint, this is the race where you show the world what you’re made of.

Round up your crew for our Sprint & Olympic Relays, or fly solo to claim your glory.

The Perks of the Podium
Every athlete who crosses the line earns a finisher medal, but we’ve got something extra for the front-runners. We’re awarding custom pint glasses to:

Sprint & Olympic: Top 5 in each age group.
Super Sprint: Top 3 in each age group.

Don’t miss out on the swag: Register on or before August 1st to guarantee your official race T-shirt. After you crush your finish, stick around for the post-race meal, the celebration, and the awards ceremony. Lake Meridian Park is the ultimate spectator-friendly venue, so bring the family—there’s plenty of room for the kids to play while they cheer you toward the finish.

 
Complete the Journey: Earn The Trident
One race is a challenge. Three races is a legacy.

To honor the athletes who grind with us all summer long, we’ve created The Trident. This isn’t just another medal—it’s a custom-crafted, heavy-duty trophy designed to recognize pure grit and consistency.

To claim the steel and the glory, you must complete the journey through all three iconic 2026 RTB stages:

1. Black Diamond Triathlon (The Opener)
2. Lake Meridian Triathlon (The Big Stage)
3. Bonney Lake Triathlon (The Grand Finale)

When you cross that final finish line at Bonney Lake, the Trifecta Trident will be placed in your hands—the ultimate symbol of a season well-fought.

 
The Grand Finale: Bonney Lake
While Lake Meridian is our biggest party, Bonney Lake is the perfect ending. We’ve revitalized this classic course with the RTB standard of excellence to give your season the finish it deserves.

A Pristine Course: Dive into the clear waters of Lake Tapps, hammer through the rolling farmlands of Pierce County, and finish your run under the watchful gaze of Mount Rainier.
The RTB Vibe: Expect a seamless experience from packet pickup to the final celebration. We’re turning up the volume to make sure your 2026 season ends with a roar.

One Season. Three Races. One Legendary Trophy. The bar has been raised. Complete the journey at Lake Meridian to keep the dream alive, then lock in your spot at the finale to claim your Trident.
