What are the factors which will affect the Race Power Calculator result?

There are three kinds of predictions that the Race Power Calculator can make and each of these three predictions has different requirements.

Prediction Type #1: Predicting a recommended power target based on a race course

Your running data from the last 90 days need to meet the following requirements:

You must have:

1. A valid racecourse uploaded via PowerCenter
2. At least 1 workout conducted around your Critical Power 
3. At least 1 workout conducted around the intensity for your target race distance
4. An accurate Model Curve on your Power Duration Curve that extends from the 10-minute duration to the 20-minute duration.
   1. Note: This means that you must have a well-balanced Power Duration Curve and max efforts around the 10 to 20-minute duration. For example, a max effort in the 7-minute duration would be effective in modeling your 10-minute duration and a 25-minute activity would be effective in modeling your 20-minute duration. Alternatively, a max effort in the 15-minute range may also effectively model your capability from the 10 to 20-minute duration.
5. Have an accurate Critical Power
   1. Note: If you use auto-calculated Critical Power, your auto-calculated Critical Power likely will be accurate if you meet requirement #3 by having a maximum effort near the 10-minute duration and the 20-minute duration.

Prediction Type #2: Predicting a race result time based on a power target 

You need to have collected sufficient data running near that power target within the last 90 days. This will allow the Race Power Calculator to effectively convert a power target to a predicted time result on a racecourse.

Prediction Type #3: Predicting a power target required to achieve a target race result time

You need to have collected sufficient data running near the pace target required to achieve that result time within the last 90 days. This will allow the Race Power Calculator to effectively convert a target race result time to a power target.
