T-Time for Swimming
Your T-Time is a method for determining how much rest you get for a repetition of swimming. It is based on your general fitness and ability to swim a repeated 100m effort. It is not based on your maximum swimming pace or fastest swim speed.
It is easiest to explain T-Time by giving an example e.g. your coach advises you that your T-Time is two minutes flat (2:00) and your set involves swimming 15x 100m on T+15sec. Your T-Time is 2:00 plus the 15 seconds equals 2:15 and that is how often you start each repetition. If you finish your first rep in 1:55 that leaves 20 seconds rest as you wait for the clock to get back around to the 2:15, your next rep might be 2:00 which means you now only have 15 seconds rest and so on.
|Rep Number||Start Time||Time to swim 100m||Rest prior to starting next rep||Start Time for next rep|
Figure: Hypotetical Example of a Swimmer with a T-Time of 2:00 conducting a session of 15x 100m on T+15
If the distance of the repetitions was based on 50m reps the time used might be ½T+10. For this swimmer half T is half of 2:00 equals 1:00 plus the 10sec equals 1:10. There fore they start each rep every 70 seconds.
If the distance of the rep was say 200m a session might be something like 8x 200m on 2T+20sec. In this case we are doubling the T-Time and adding 20sec, therefore 4:20.
