California Triathlon Chapters


California Triathlon coaches routinely volunteer their time in the community to teach the sport of triathlon.  Each year, several $500 Cal Tri Coaching Scholarships are awarded to active members who successfully complete the USAT Level 1 Coaching Certification, volunteer to coach 1x/week for a year and proudly represent the team on race day and in the community.  After their commitment is fulfilled, California Triathlon reimburses award winners $500 to defray the cost of their USA Triathlon certification.  Our coaches are professional in non-triathlon related endeavors but several will take a private coaching client if there is a good fit.

Kim Degen, USAT Certified Coach, Orange County Chapter Lead
While sports have been a huge part of my life, it wasn’t until 2009 that I started running and specifically trail running.  I would wait until 2011 before I would do my first triathlon which would change my life forever. Over the next next 5 years, I would train and race everything from Sprints to Ironman triathlons and totally fall in love with the triathlon lifestyle. My passion for triathlons led me to becoming a certificated coach so that I could share my experiences and help others accomplish their goals.

Mark Terry, USAT Certified Coach, Sacramento Chapter Lead

I was introduced to triathlon in 2005 with a challenge from a co-worker.  At the time I was a 215 pound bodybuilder, didn’t own a bike, and couldn’t swim more than 25 yards without stopping.  Six weeks later I completed my first sprint distance event and found a new passion in the process.  Although I have led a healthy and active lifestyle my entire life, triathlon provided me with new and inviting ways to challenge myself.  Over the past decade I worked my way up from sprint to Iron distance and have competed in 3 Ironman events as well as many Half IM’s, Olympic, and sprint distance events.

In 2010 my passion for the sport, and desire to help others learn from my experiences, led me to coaching.  My personal mission is to help athletes of all ages and abilities accomplish their goals and so I am looking forward to being part of California Triathlon to help me accomplish this mission.


Roberto Lepe, Inland Empire Chapter Lead

I haven’t stopped ever since.
