Reading the Pace Clock
Information by Team Unify

The clocks that we use during practice are digital. The examples below use analog clocks. The main difference for our swimmers is the analog clock uses 60, whereas the digital clock goes to 00 after each minute. However, the explanations below should still help our swimmers.

By thinking of the clock face as a pie, it becomes easier to visualize into segments and keep track of your swims and sendoff times. Listed on this page are some basic intervals along with an explanation of how to figure your next repeat.
60 Second Intervals

Interval sets that are exactly one minute (or two minutes, three minutes, etc) are easy! Whatever number you start the first swim on, will be the same number for all repeats in the entire set. For example, if you leave on the "top" or the 60 second mark (00 on our digital clocks), on all the following repeats you will push off on the 60 again. If you leave on the "bottom" or the 30 second mark, on all the following repeats you will push of on the 30 again.

When using interval sets that are either 30 seconds (or end in 30 seconds: 1:30, 2:30, etc.) you will always leave on one of two numbers. Those two numbers will be directly across from each other on the clock. For example, if your interval is 1:30 and you leave on the 60, you will push off again on the 30.
20 or 40 Second Interval

Intervals of either 20 or 40 seconds slice the pace clock into thirds. This means you will always leave on one of three numbers.

If your interval is 20 seconds (or 1:20, 2:20, etc.) your numbers will rotate clockwise. For example, if your interval is 1:20 and you push off on the 60, your next push off would be at the 20, then the 40, and then the 60 again.

If your interval is 40 seconds (or 1:40, 2:40, etc.) your numbers will rotate counterclockwise. For example, if your interval is 1:40 and you push off on the 30, your next push of would be at the 10, then the 50, and then the 30 again.
15 or 45 Second Intervals

Intervals of either 15 or 45 seconds will split the clock into fourths. This means that you will always leave on one of four numbers.

If your interval is 15 seconds (or 1:15, 2:15, etc.) your numbers will rotate clockwise. For example, if your interval is 1:15 and you push off on the 30, your next push off would be at the 45, then the 60, then the 15, and finally the 30 again.

Intervals ending in 45 seconds (1:45, 2:45, etc.) will have sendoff numbers that rotate counterclockwise. For example, if your interval is 1:45 and you push off on the 60, your next push off would be at the 45, then the 30, then the 15, and finally the 60 again.

In both cases, you will notice that the sendoff numbers will alternate ending in 5 or 0
10 or 50 Second Intervals

Intervals of 10 seconds (1:10, 2:10, etc.) and 50 seconds (:50, 1:50, etc.) are easy!

For 10 second intervals, your next sendoff always advances in a clockwise rotation. For example, if your interval is 1:10 and you push off on the 60, your next push off would be at the 10, then 20, etc.

Sendoffs for 50 second intervals always retract in a counterclockwise rotation. For example, if your interval is 1:50 and you push off on the 30, your next push off would be on the 20, then 10, etc.
5 or 55 Second Intervals

Intervals of 5 seconds (1:05, 2:05, etc.) will always advance one number. For example, if your interval is 1:05 and you push off on the 60, your next push off would be at the :05, then 10, etc.

Intervals of 55 seconds (1:55, 2:55, etc.) will always retract one number. For example, if your interval is 1:55 and you push off on the 30, your next push off would be at the 25, then 20, etc.
