The 3 Minute Aerobic Test estimates your aerobic capacity, or put more simply, your ability to work consistently at moderate to high intensity for extended periods. It is important both for endurance cycling and for your general fitness. During this test we determine your average power (in watts) and your maximum heart rate which are then used to define your personal Training Zones. This test is a precursor to other tests (either repeat assessments or Ramp Tests) that you can use to track your progress throughout the season.
