40th Annual Los Alamos Triathlon  


Join us in the once "Secret City" to celebrate the 40th Anniversary of the oldest, continuously running triathlon. The Los Alamos Triathlon is a sprint triathlon with a unique format of Bike, Swim, Run and is held at a starting elevation of 7,400`. The course is challenging with a rolling bike course that starts in town and takes you out along an open course surrounded by mountainsides and forest; returns for a 400 meter pool swim; and ends with mildly flat, with some inclines, run.


The LAC PROS Division would like to thank all of our Participants, Sponsors, Volunteers, and Los Alamos County staff who helped make the 40th Annual Los Alamos Triathlon another amazing event.
Race results can be found at the following location:

KUDOS to everyone! See y'all in 2015.
