T-pace stands for a Test-Pace that is used most commonly in swimming (but sometimes in other sports). Defining a T-pace allows a coach to vary the effort levels within a swim session. It is a way of telling a swimmer to swim easily and slowly or to swim at race pace. Depending on how it is defined in a plan, T-pace can also mean Threshold pace and this is how it is used here. For a novice swimmer taking part in a sprint triathlon T-pace should be the pace that can be held for 750 m. For an experienced, long or standard distance triathlete then T-pace should be the pace that can be held for 1500m.
