I just started riding again this spring, first on a Trek Emonda Sl6 and then a Domane SL7 and I just set up my Wahoo Kickr. I started yesterday by doing about an hour on Innsbruck. Then today I figured I should try to find out my FTP, so I did the short Test (45min). I completed it best I could, but at the end it says my FTP is only 114. I am in Erg mode for the FTP.
I am 50 yrs old, but I think I’m in decent shape. I typically ride 4 days a week 15 miles per ride, and weekends 25 miles, averaging about 15.5 mph. Prior to this I worked out at the gym, mostly weights and light cardio. I’m 5’10 and 165 lbs, male.
Possibly related: I notice my Garmin will say I’m doing 20mph but on the screen Zwift says I’m only doing 8mph (just an example). Was I supposed to do some sort of calibration prior to my first ride? Or am I really not as in shape as I thought I was?
Thanks in advance for any advice.
