    Literature calls for swim time trials to swim a fixed distance to calculate zones. Any suggestions for swimming in a swim spa where pace or distance aren’t necessarily known.

    I am able to capture HR data and time.

    If you have a Garmin device that supports open water mode, then you can use any of our swim workouts without a standard pool, including the test workouts.

    However, if your spa in indoors, which I suspect, this option is not available to you.

    So, you’ll just have use feel and a best guess for an indoor spa. Check out the swim zone calculator at and give your best estimate of each zone. Then, when the workout called for “Zone 3” you’ll estimate a Zone 3 intensity and perform the interval for the estimated duration. For example, if you are asked to perform 200 meters at Zone 3, and your best guess is that your Zone 3 is 1:51 to 1:56 per 100, then you’ll swim at a Zone 3 estimated intensity for 3:42 to 3:52.
