Melbourne Based Triathlon Coaching

Fluid Movements Head Coach and Founder, Sean Foster began coaching in 1996 in the role of swim coach for EPS Triathlon under the direction of Coach Tony Benson and quickly improved a squad of over 80 swimmers, finding his passion for coaching. After completing his first ironman in Forster (NSW) in 1999 where he placed 11th overall and 1st age grouper, he took on co-ordination of the EPS Ironman program. In 2003, Fluid Movements Sports and its full triathlon program was established following a great apprenticeship under Tony Benson.

Fluid has grown to become one of the most successful and respected training squads in Victoria. We pride ourselves on providing high level, individual coaching for all abilities, from our 6 week Beginner Course through to Elite Age Group.
