Featured Team D3 Athlete

Kalee Tyson

Coached by Brad Seng, USA Triathlon Certified Coach

Kalee’s ability to stay focused and desire to get the work done when having to make adjustments due to “life” happenings allowed her to make continued gains throughout the season.  Her coach, Brad Seng, was extremely proud of her ability to have a strong mental psyche in Cabo which put her in a position to secure her Worlds slot.

Athletes who are coached 1-to-1, follow a Custom Training Plan, or use one of our Pre-Built Training Plans are considered members of Team D3.  Athletes can become part of the Team at any time through our coaching services.  These athletes experience the double power of coaching and camaraderie.  Once a year, in the fall, we publicly invite athletes who are not currently coached through D3 to join Team D3 with the understanding that they will support the Team the following year. 

Team D3 athletes embrace our coaching principles of Desire, Determination and Discipline and are great ambassadors of triathlon.  They also share in the camaraderie and benefits of a diverse, passionate group of athletes. Team D3 athletes range in ability from beginner to elite, and they train in home towns that span between Boulder – New York City – San Diego – Costa Rica – Dubai – and so many places in between!  With an incredible 19 years of triathlon coaching and team management expertise, we use a mix of technology, social media, events, partners and of course, racing to bring athletes together – no matter where they live. 

Take a peak at our Team!
