To continuously improve in swimming, it’s important to routinely measure your performance in training. Test sets are a fantastic way to track your progress because after all, what gets measured, gets improved!

What is a Test Set?

A Test Set is a specific workout (or set) designed to collect data on your development and improvement in a particular energy zone. This is the best way to track progress across the season and in your swimming career. Test sets are best when done intentionally and as a part of a greater seasonal training plan. You can learn how to build a seasonal training plan here.

Test sets need to test a specific energy zone to be effective. Often times this will either be an Aerobic Test Set, or an Anaerobic Test Set. It’s most beneficial to have these laid out ahead of time so they fit into your weekly or monthly plan. We can categorize test sets into one of three buckets:

  1. Pure Aerobic – EX: “30 Minute Swim”, test EN3 (Aerobic Threshold)
  2. Anaerobic – EX: “10 x 100s @ 1:30 Best Average”, test SP1 (Best Average)
  3. Pace – EX: “4 x 50s @ 1:00 200p”, test SP2-SP3 (Race Pace)

Some training programs and philosophies apply a progression to the concept of test sets. An example could be doing a test set every week or every other week with a varying distance and amount of rest. This prevents burn out and keeps things mentally engaging. It’s also more beneficial to apply a progression if your goal is to compete in a specific event at the end of a training cycle. Below are progressions for each of the three buckets described above:
