HOMEBASE: Noosa, AUS & Boulder, CO

A Kiwi triathlete who resides in Noosa Heads, Australia and Boulder, Colorado. Millward has been racing pro since 2006 and currently specializes in long distance triathlon, from half ironman to full ironman. He raced in the Ironman World Champs in 2015 and 2016.

When not racing he finds balance in life and shares his journey with his girlfriend Alise Selsmark. Together they manage a team of like minded age group triathletes, called The Cupcake Cartel. They are a predominately American/Australian team that come from all walks of life. The common denominator of the team: Humor.

FAVORITE POWER WORKOUT:  “60mins of Ironman power—for me: that’s 240 watts—at the end of a long ride. So at the end of a ride with a total time of 5.5-6 hours, or 170-180km, I’ll do the last hour at a steady 240 watts.” 


WHAT’S ON CAL’S DASH:  Power, avg power, lap power, cadence, lap time or alternatively just power 3s/time/cadence. “I’ve always been a slow-twitch muscle kind of guy, and Ironman is about staying steady and knowing your pace.”

HAPPIEST MOMENT TO HAVE STAGES: “You do all this training, but race day always can turn our differently. When I completed my first Ironman in 2015 my average power for the bike read 222 watts. I felt like all the stars had aligned and all the training had paid off.”
