Los Alamos prepares for annual triathlon

The Los Alamos County Triathlon is set to make its return for the 43rd time later this month, making it one of the oldest continuously running sprint triathlons in the country.

On July 29, Los Alamos County will host three separate triathlons: the official triathlon, the Kids Triathlon and a new event, the Junior Triathlon.

The Los Alamos County Triathlon is unique, as it has a format of bike-swim-run, as opposed to the normal format of swim-bike-run. The County’s Recreation Programs Manager Dianne Marquez said a variety of factors have led to that format.

“The big reason is that we impede two of the major intersections in town at Trinity and Diamond, and Canyon and Diamond, so we want to get cyclists on and off the road as quickly as possible.”

By having the cycling leg first, organizers can make sure the road is blocked off for as little time as possible, making it more convenient for participants and the public.

Marquez added that she has asked participants if they would like to see the format become more traditional, and has learned that they seem to prefer the current format.

The sprint triathlon consists of a 12-mile bike course, followed by a 400-meter swim and a three-mile run.

It will be a chip-timed event with awards given out to top finishers.
