Overview

Dive into history and nature at the 43rd Annual Hagg Lake Triathlon & Trail Festival, a celebration of tradition and stunning landscapes. As one of the nation’s oldest and most beautiful triathlon courses, this event offers an array of options, including Olympic & Sprint Triathlon, Duathlon, Paddle Tri, AquaBike, and Off-Road Sprint Triathlon. Trail enthusiasts can participate in the Half Marathon Trail Run and 5K Trail Run, with relay options perfect for friends, family, and co-workers.

The roots of modern triathlon trace back to San Diego in 1974, and Hagg Lake joined the scene seven years later as part of the Bud Light Triathlon Series Tour. Drawing about 500 athletes initially, it has now become a summer staple with over 700 participants. The course’s allure lies in its rich tradition and scenic venue, offering a true test with rolling hills on both the bike and run legs. Join us at Hagg Lake, where history meets athleticism, and experience the course that has witnessed the triumphs of many greats in the sport of triathlon.
