20 MINUTE FUNCTIONAL TRESHOLD POWER TEST:
By spliting the 20-minute effort into 4 segments, you can adjust your effort to your muscular feedback. Manage your effort equally between the segments, this will help prevent a common tendency of having a surge of power at the end of the test. Ideally you should have the same pace during the 20 minutes. If you have a Training Peaks account, use their email system that lets you know your new FTP.
