Carol

"Nick's swim analysis sessions are fantastic. He has a great way of explaining how to break down each part of the stroke without it being overwhelming. The support drills help you take what you have practised during the session back to your local pool. I would highly recommend speedy swimming for anyone who is looking to improve their stroke."

Athlete Testimonials

Malik

"I've been coached by Speedy Swimming for several years now and cannot speak highly enough of them.
Have improved my pace and technique by a large degree and has also reduced stress and injuries. Sessions are fun but focussed. Much recommended!"

Mr Clayton

"You'll be very happy with the results Nick can help you to achieve, and on completing an Ironman I'm hoping to continue working with him to achieve a slot on the Team GB Age Groups for a sprint or standard distance race in either duathlon or triathlon."
