The Performance Calculator

There are 3 ways to assess current fitness levels.

1. Current race time. Enter a race distance and time into the calculator and receive an estimated VO2 Max and the equivalent performance for other distances. The more recent the time the better.

2. Past race time. Choose a time from when the athlete was in a state of similar fitness. If there are multiple race times, choose the one that best represents the course and target distance.

3. Pace Fitness Time Trial. For beginners and those who do not have a recent or comparable race time.

   Runners: Visit a track and run 3 miles (12 laps) as best you can. Record the time. Give it a strong effort, but don’t overexert yourself. You want to start your training efforts where you are today. In the future, you can re-test yourself and adjust your plan and pacing accordingly.

   Beginners: for those who cannot manage 12 laps yet, do just 4 laps (~1 mile) as best you can, even if you need to jog/walk.

   Enter your time and distance in the Performance Calculator . This will give you an estimated VO2 max for your effort at that distance establishing a starting point for the Wizard. It will also show you what target time* you can reasonably expect for your goal race.

   *The Performance Calculator is more accurate when events with similar aerobic/anaerobic proportions are compared, e.g. a time over 800m cannot accurately predict a marathon time, or vice versa.
