When my "off-season" plans of improving my overall swimming technique were sidelined by a broken collarbone, I turned to Mark for coaching. Mark told me most of his athletes enjoy the swimming aspect of the Ironman the most, I thought that I had a long way to go before I felt that way. After spending the summer swimming with SWIMfast in the Open Water Class, swimming was the most enjoyable aspect of training and by far the area that I exceeded my own expectations during the completion of my first Ironman. What impresses me most about Mark is his ability to make the workouts challenging and fun at the same time. The family of athletes at SWIMfast are a close group of people from various backgrounds but similar goals. Mark is one of the most talented coaches I have worked with and look forward to continuing my improvement in swim technique in his Masters Swim Class. When it comes down to it, Mark is a great coach and great person.
