Annual Los Alamos County Triathlons Return July 28

Back for the 44th year, the Los Alamos County Triathlon is Saturday, July 28, along with the 25th Annual Kids Triathlon and the 2nd Annual Junior Triathlon.
The event is known for its high altitude competition, and is held at a starting elevation of 7,400 feet.
“Whether you’re a first time competitor or one of our regulars, we hope all will come and compete in our high altitude setting,” County Marketing Manager Kelly Stewart said. “While Olympic and professional athletes often train in Los Alamos due to our incredible altitude, there are competition levels for all ages and all skill levels to make the event fun for the entire family.”
The Los Alamos Triathlon is one of the oldest, continuously-running sprint triathlons in the Nation that has a unique format of Bike-Swim-Run. It offers a challenging 20 KM bike course with rolling hills, surrounded by beautiful mountain vistas. The bike leg is followed by a 400-meter pool swim and ends with a 5 KM run that heads north on Diamond Drive and ends at the Aquatic Center. This is a chip-timed event with cash and individual age group awards.
The Kids Triathlon is for ages three to ten and is a non-competitive, fun and continuous race. Participants can use pushbikes, tricycles and training wheels on the bike course. Flotation devices and life vests are allowed in the pool. Every finisher receives a participant medal in this race, which is designed for fun and fitness.
Back for its second year is the Junior Triathlon for ages 10–16, which allows participants to transition to a competitive and timed event. This is an abbreviated Los Alamos Triathlon course with a 6.4 KM bike, 200-meter pool swim and 2.4 KM run. This event has medals for 1st– 3rd place in the age groups and is a great introduction to the competitive world of multi-sport events for youth.
