While I have only been a professional triathlete since 2007, I have been a lifelong competitive athlete competing as an elite NCAA Division I swimmer and runner at University. Post-college, I competed as an elite marathon runner while working full-time and finished 3rd in the Philadelphia marathon in 2:41 so I understand the work/life balance that many age groupers struggle with on a daily basis.

I have been racing triathlons since I was 29 years old when a diagnosis of osteoarthritis forced to me abandon marathon running for triathlon. I started my career racing ITU Olympic distance races. During this time I received tremendous support from USAT and was able to win a Pan American title and compete in the World Championships. In 2008, I started racing 70.3 events and had success quickly with a 2nd at the 70.3 World Championships in 2008 and 2009. After an injury plagued 2010, I joined Brett Sutton in 2011 and embarked on my Ironman career. Together with Brett, I have won 11 Ironman titles, an ITU long distance world title, and finished in the top 5 at the Ironman World Championships.

While I am just embarking on my coaching career, I have the best mentor in the sport with Brett Sutton. As an athlete, I have had the opportunity to learn from the top triathlete coaches in the world. My goal is to become one of the USA’s top age group and elite triathlon coaches and pass on my years of knowledge to help as many athletes as I can.
