If you've noticed that your power-duration curve doesn't display, or that there are only dashes where your phenotype, Pmax, VO2max, TTE, FRC, and mFTP should be in the Hero Bar (see the image below), you probably have some bad data in a workout or two. You'll probably also be unable to calculate training levels, and your mean max power curve may display jagged drops and jumps.
Fortunately this is simple to fix. Click here for instructions on finding and fixing bad data.
