Coaches and Officers

Head Coach: Brad Seng 

Lives in: Boulder, CO


Originally from: Bloomfield Hills, MI.


Studied: BA in Psychology from Albion College, home of the mighty Brittons, MA in Sports Administration from Wayne State University (both in MI).


Favorite Triathlon Discipline: Running comes most naturally to me, having chased a soccerball for years while playing through college. I used to despise running though, but now relish the opportunity to play a big game of Pac-Man while running down the competition in races.


A few words about CU Triathlon: "The history and tradition of excellence of our program is impressive, but even more so is the camaraderie and community found within the team. A group that encompasses a wide variety of athletic backgrounds and abilities, the team fosters an atmosphere of support and encouragement while challenging individuals to be their best. There are numerous opportunities for members to grow athletically, emotionally and intellectually all within a fun, competitive environment. Boulder is the mecca for endurance athletes and the University of Colorado Triathlon Team is an integral part of this larger community. No other location can match the resources, training opportunities, good weather and density of elite athletes and active individuals that Boulder has to offer."

Assistant Coach: Dave Sheanin

Lives in: Erie, CO

Originally from: Woodland Hills, CA

Studied: Psychology at UC-Irvine (go anteaters!) and MBA at CU-Boulder.

Favorite Triathlon Discipline: Swim for sure. Love the water but it's a curse--no one wins a tri in the swim, but I'm willing to keep trying.

A few words about CU Triathlon: "I love/hate living and training in Boulder. It's awesome to rub shoulders with some of the very best in the world as well as tons of really inspirational amateurs giving it their best. But training rides can easily turn into road races and runs into track meets. Sometimes it feels like it's competition all the time around here. Still, I would never trade the fantastic people, beautiful geography, and relaxed pace for anywhere else.

The CU Tri Team is a unique group. The championships are nice but that's not what makes this team special. We're a family and I've never seen such closeness among members of a group or team of this size anywhere else. It's hard to describe but you all make each other better every day you're together--on and off the race course."
