Publisher, President

Since joining Strava in the Fall of 2012 it says I have ridden over 21,000 miles, ran 3,200 miles and swam 465,000 yards preparing for triathlons (obviously) and numerous biking events, but more importantly, exploring roads and trails all over Colorado (mostly)—my happiest of places. Cycling is my passion and growing up in Golden, I still find new places to explore and I like nothing more than sharing them, and my passion—especially on 303cycling and 303triathlon. Sometimes I write a column with my pen name, TriHearter…that word says it all. I wear my heart on my sleeve and always give it my best. I also love to work with organizations who want to market to our very targeted audience of athletes and enthusiasts—let me explain how sometime! Happy riding and training!

Editor, Celebrity Correspondent

A Colorado resident since 2001, Khem grew up playing sports in school because they were fun, but often spent time warming up the bench. She got into running not too long after moving to Denver. After completing her first marathon, she realized that slow-twitch muscle events were her jam. She got started in triathlon through Team In Training in 2010 after completing several marathons with them and coaching their marathon teams. The Koolaid never tasted so good. After a few years of training and racing she was all in with swim-bike-run, finished her first 140.6 in 2012 (IRONMAN Canada-Penticton), and made a natural transition to coaching triathletes shortly after. In 2015, Khem was one of five athletes chosen nationwide with the Team in Training program to fundraise (over $300,000!) for The Leukemia & Lymphoma Society and race at the IRONMAN World Championships. She has served on the board for the Rocky Mountain Triathlon Club, coaches with Mile High Multisport, and races for Palmares Racing and the USA Triathlon Foundation. If she’s not racing, you’ll often find her out supporting her friends out on the race course, and always with a big smile. During the winter she enjoys hitting the slopes on powder days and dabbling in cyclocross. Her favorite food group? Bacon!!

Outside of competing in triathlons, Kenny is an accomplished videographer, and co-owns 5280 Elite, producing many inspirational and commercial projects. He is a regular contributor to 303, and will be joining the Kona team once
