Dennis 2014 Nashville Tri

Dennis, Nashville Tri

Coach Mary is amazing!  She got me ready for my very first triathlon at age 40 with a fantastic training plan, superb coaching, and incredible patience.   was really nervous about the swim portion of the race, but Mary worked tirelessly with me to get me ready (both physically and psychologically). On race day, I felt very prepared and thoroughly enjoyed the experience.  I cannot thank Mary enough for helping to make this first experience so terrific!"

Coach Mary provided expert guidance and a positive attitude in coaching our group of female healthcare executives.  We all came from different bases of fitness, and athletic backgrounds, and Coach Mary helped us all uncover our inner athlete!

Coach Mary is my “secret” weapon. She has helped me tremendously in my Triathlon journey as a 55+ year-old age-grouper.  She takes the guess-work out of my training and saves me tons of time while keeping me motivated and providing accountability.  She understands my time constraints and how to pull everything together into a manageable plan to fit into my busy schedule. 

Last season I had several podium finishes, completed my first 70.3 Ironman event and qualified for nationals!
