Hello,
I’ve calculated my power zones using both tools and there appear to be some differences. My zones using the 80/20 calculator with an FTP of 212 compute the following: Z1-106-148, Z2-148-176, ZX-176-193, Z3-193-212, ZY-212-216, Z4-216-233, Z5-233+. My strava zones are as followed: Z1-1-116, Z2-117-159, Z3-160-190, Z4-191-222, Z5-223-254, Z6-255-318, Z7-318+. I primarily use Strava as a tool to capture my training data, but the zones are quite different especially when at the end ranges of the zones. I’ve currently been following the strava zones when creating workouts. Any suggestions on if there’s a better one to follow or if the main purpose should stay below the top end of Z2 for any low intensity?
