Email Coach Susan

Susan came into the sport of triathlon at the age of 24 as a successful collegiate swimmer that would bike and run with friends just to stay in shape. She was a member of the USA Resident Triathlon Team in its second year, in 1997, when she turned pro and started racing on the International World Cup Triathlon circuit.  

After the birth of her daughter Sydney in 2000, she set her sights on making the 2004 Olympic team. Along the way, Susan competed in the Ironman World Championships in Kona in 2002, which broadened her aerobic base going into the 2004 Olympic Triathlon Trials.  She achieved her goal of making the 2004 Olympic Triathlon Team and represented her country proudly in Athens, Greece.  

After earning her Olympic Bronze medal in Athens, Susan decided she wanted to use the knowledge she had gained throughout her racing career to teach other athletes how to reach their full potential.  

She is now a high performance endurance coach and masters swim coach and works with triathletes of all abilities, disciplines and distances. 

Wanting to explore additional methods of pushing her body to its physical and mental limits, Susan ventured into mountain bike racing in 2008 and received the honor of top female in the Leadville 100 Mile Mountain Bike Race. 

Susan has over 14 years of competitive swimming and over 15 years of elite triathlon racing experience which makes her well-rounded and well-versed to lead athletes to optimal performance.
