Practice deciding
    The plan says Mark should run on the treadmill for 15 minutes with an HR within threshold (which you have calculated to be between 135-150). You will set speed and altitude to maintain appropriate intensity.
    1. Mark reaches threshold in 2 minutes.


    2. At 5 minutes Mark's HR is 155.

    3. At 10 minutes, while his HR continues at threshold, you are forced to decrease Mark's intensity to a walk.


    4. Sam does the same plan and has the same stats, and at 10 minutes his HR is 125.
