"I was quite nervous about taking on the challenge of a triathlon but after signing up for an Ironman, buying a tri-bike and interviewing several coaches (in that order), I chose Colin as the right coach for me. I could not have been more pleased with my decision." - Lydia J.

"Colin helped me take both my overall fitness and my triathlon performance to a new level. He really listens to what your goals are and helps work around your schedule to tailor a training plan that fits your life and pushes you to do more than you thought possible." - Anri B.

"Leslie was able to personalize a plan that transformed my life." - Roger C.

"Each Wednesday, Trent and I would discuss the previous weeks results and the upcoming weeks plan (and purpose). We would talk about everything from pedal/cleat/shoe fit to nutrition. I found the entire process to be such a great learning experience." - Michelle M.

"Leslie delivered. She provided me exceptional guidance throughout Ironman training and for the race. With Leslie's coaching, I maintained high energy levels during the months of training prior to the race and then completed my Ironman ahead of goal with excellent energy, no cramps, and no stomach issues." - Matt T.
