“I hired Colin because I wanted to be sure to reach my goals, including to learn how to swim and to become an Ironman someday.  Little did I know at the time, just how fortunate I was to have found such a gifted coach. He took me from not being able to swim even one lap of a pool to being able to conquer the full distance of an Ironman. Colin has not only transformed my athletic ability, but has changed my life in so many ways.  I’ll be forever grateful for his leadership and for helping me create such a rewarding life”


“I have been receiving swim instruction from Colin for 6 months .When I first started with Colin I had already completed a few sprints,a few Olympics,and a Half Iron Man.I was averaging around 1:50 per hundred when Colin first met me.After my first 2 sessions with Colin I was more effecient,faster and more confident in the water.He gave me significant technique critique and immdeately had  me happy That I had chosen to seek his instruction.After 4 months ,I swam a22:30 1500m in my first olympic race of the season(1:30 per undred).I had completed this same swim course a year earlier in 28:30.I was 6 minutes faster!!Not only was 16 minutes faster but I wass less tired getting out  of the wayer than I was the previous year.Colins focus on techniques keeps you fresh and injury free; two things that every multiport athelete has a challenge dealing with.I will keep working with Colin untill he tells me I have it 100% right.He always has things to tell me to make me better.I higley reccomend working with colin if you want to be faster in the water,be more effecient and get out os the water ready for the bike”

“As an adult  who was new to the concept of swimming ina competitive field Coolin helped me with a verity of skills .Through pool sessions and structured workoutsI was able to gain a huge amount of confidence and become more   compfrotable in the water than I ever thought possible .With his help and instruction I was able to go from swimming ! lap in the pool to over 1 mile in the open water .”

“Colin is agrate swim coach whether you want  to work on technique,build up endurance or swim a faster race.He will help you get better and build cnfidence on it all! I first met Colin when I enrolled in his tri swim program.Before that i only knew breast stroke and could barely swim 25 Yards freestyle.Within a span of a few months with jusr the weekly lessons ,I swam my first 1 mile race at the Lobsterman tri.Since then i have been following Colin’s  swim plans and vastly improved my swim speed and endurance and done a few more Olympic distance and 1/2 ironman traithlons.I would higly recommend  Colin if You want to crush it all your races!”

“I was very fortunate to come across a swim class at the Nashua YMCA 3 years ago,taught by Colin Cook.At that time I considred myself a beginner swimmer ,and I wonderd how  some swimmers coukd say”i’m just doing an easy 1,000″.Today,I am disappointed if I don’t swim 2,000 yards ina workout!Colin improved my technqiue,taught me how to relax,encouraed me to be myself and to strive to do my best.Colin is  always positive  and supported towards his students, and he is someone I would highly recommend.As a secondary benefit,I learned a great deal about Tri-training from Colin and in 3 years,I’ve completed 10 sprint events.at almost 66 years old,i have never felt better and i am in the best sahpe of my life thanks to colin.”

“I can’t say enough positive things about having Colin Cook as a coach. He started with a visual evaluation of my swimming and built my program from there. His approach is straight forward and easy to follow. We slowed things down to go fast in the end. His knowledge of techniques, workouts, and training tools are second to none. When you have a coach like Colin you can breathe a sigh of relief and trust the process he will get you where you want to go from beginner to Elite it doesn’t matter.”
