Featured Team D3 Athlete


Coached by Jim Hallberg, USA Triathlon Certified Coach

Oceanside 70.3 2019 was Dana’s best race in many years. There was an important sequence of events in her training that helped to make that happen. Her final result was 6:11 for 18th place in her age group (50-54). She ran a 1:59 on the run and the metrics of her race were nearly perfect!

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. They 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 Canton of Vaud, Switzerland – New York City – Boulder, Colorado – and – San Diego, California. Beyond our coaching, we use a mix of technology, events, and of course, racing to bring athletes together. We recognize and celebrate our Team throughout this page.
