Tuff Fitty was established in 1991 and held its first AGM in November of that year.

This set the standard for the club whereby a committee of members runs the club for the benefit of its members backed by a written constitution. Being one of the earliest Triathlon Clubs in the South of England, membership growth was initially rapid.

The club has grown to its present level having 150 members of all abilities from beginner to National level. The club holds its own championship that is open to all members.
