Garrie Prosser

Triathlon Coach

Garrie Prosser, Triathlon Coach

Garrie completed his first triathlon in 1990 finishing almost last! Since then Garrie has completed more than 250 events over every distance often finishing on the podium. Latterly, Garrie has transferred his passion and commitment from training and racing towards coaching with a similar level of success.

Garrie now has over 16 years of experience in coaching triathletes of all standards to achieving their goals. Garrie coaches both groups and individuals, however, his passion is working one to one with athletes.

"My goal is to improve your performance by analysing your movement and your body."

Since first meeting the Trinamics team I have been impressed with the commitment and enthusiasm to develop a new and exciting provision for triathletes of all abilities.
