Seattle Triathlon Group logo

The Seattle Triathlon Group is a 501(c)3 public charity founded by the leaders of the Seattle Green Lake Triathlon Group as the new home for triathletes in the region. The group was created to reflect the vibrant diversity of our membership spanning the entire Greater Seattle Region, the desire to be more inclusive, and the goal of having a stronger brand with more recognition. We aim to provide education and training opportunities to individuals by offering coaching, instruction, training, and courses on triathlon-related skills and subjects, and facilitating amateur engagement and competition in national triathlons.

We're still working on getting our web presence fully online, but in the meantime, you can Join as a Paid Member here. Don't be afraid to reach out if you have questions.

Winter Training Series

 As the weather cools, we continue to cheer on a few members still training for some late-season races. Most of our in-person training events have completed for the season, as it's now getting dark out much earlier and water temperatures have dropped. Fear not, however! We're still planning some end-of-season socials, educational training sessions, and remain active on our Facebook Group. We'll also start hosting virtual rides again for those using Zwift.
