Coach Deanna McCurdy

Deanna loves to share her passion and knowledge gained over 30 years of running and 10 years of competing in triathlon at an elite level. A former Division I cross country and track athlete, but not reaching her full potential until her late 30’s and 40’s, she understands the process of continual growth as an athlete, how to fuel passion and goals with a bigger purpose or “why”, and utilizing scientific training principles to help a person reach his/her potential while remaining happy and healthy.

Deanna races professionally as an off-road triathlete and mountain biker, is 2-time USA Triathlon Off-Road Triathlete of the Year, XTERRA age group World Champion, and was the Top American, placing 4th Overall Amateur at the XTERRA World Championships in Maui in 2017 and 2018, She also won Overall Female at the XTERRA PanAm/National Championships in 2016, 2017, and 2018. In 2019, she finished 2nd Overall Pro at XTERRA Quebec and won local races like the Winter Park Hill Climb mountain bike race, and both the Deserts Edge Off-Road Triathlon and Road Triathlon in Fruita, CO. She has also competed in Ironman 70.3 World Championships, placed in the Top 5 Overall at ITU Cross Worlds and was 2nd Overall Female at the Snickers Marathon in Albany, Georgia.

On a personal level, Deanna is mom to 2 girls, one who takes after her active parents and loves running, rock climbing, playing competitive lacrosse and skiing. Her younger daughter has Angelman Syndrome, a rare genetic disorder that affects her ability to communicate as well as contributes to cognitive, balance and coordination challenges. Having a child with significant special needs inspired Deanna to create a training and racing team in 2010 after her daughter was diagnosed, Team Miles for Smiles, and fueled her passion and “why” behind her own racing endeavors. She loves to share this passion with others, help them set big goals and reach their full potential, balance time for training with family, work and life, and become a different person as they grow and cross their own finish lines in sport and life.
