Black Diamond Triathlon - Enumclaw, Washington - Triathlon

The Black Diamond Triathlon is a Triathlon race in Enumclaw, Washington consisting of a Ironman and Super Sprint.

Nolte State Park at the base of the Cascade Foothills offers a beautiful, rural landscape for the last long course triathlon of the Pacific NW season. The courses are rural & beautiful and a great way to swim-bike-run through the last weeks of the summer multisport season.

The Long-Course triathlon begins with a 2-loop swim in Deep Lake. Athletes exit the water and ride 56 miles on gently rolling country roads with generous shoulders through the sleepy communities of Cumberland, Selleck, and Ravensdale. The roads are a favorite training ground for area cyclists. The 13.1 mile run doesn't get too far from the park and ends with a 1.4 mile loop on the forest trail surrounding the lake.

The Sprint Course is a one-loop, 1/2 mile swim, followed by an 11.3 mile bike course and a 2-loop 2.8 mile trail run around Deep Lake. For those familiar with the BDT, the sprint course is exactly the same as it's always been.

Families can enjoy a beautiful park during the day with a swim beach, kids play area (accessible for kids!), and generous picnic area as their athletes come and go through transition. After the race, everyone can enjoy a full meal, finishers medal, and an awards celebration that awards the top 3 in each age group, top 3 relays (by gender/mixed) and the top 3 overall men and women.
