Conducting an FTP Test
Before you can conduct a test to determine your functional threshold power (FTP), you must pair a chest heart rate monitor and a power meter with your device (Pairing Your Wireless Sensors), and you must get your VO2 max. estimate (Getting Your VO2 Max. Estimate for Cycling).
NOTE:
The FTP test is a challenging workout that takes about 30 minutes to complete. Choose a practical and mostly flat route that allows you to ride at a steadily increasing effort, similar to a time trial.
