A few days ago I logged onto Zwift to do a structured workout and when I started I was in my zone 1, but it was saying I was doing something like 4 wkg, so I looked around a bit to figure out what was going on and discovered my weight was set really low. Something like 100 lbs. lighter. I didn’t really think anything of it—I figured it was some bug and I updated with my current weight and forgot about it and did my interval session.
Today I am looking for a race and see I’ve been category enforced up to A. I’m normally a B (and not top of the Bs lately, at least for my ftp). I thought maybe my VO2 intervals were high enough for the zMAP number to go over the limit (which would be fine, if true), but I just checked and it’s only 4.7 wkg so I’m assuming whatever happened with my weight caused me to get placed in A? My zFTP is only 3.5 wkg. I checked zwiftpower to see if I had accidentally raced with the wrong weight and I have not (I would have noticed immediately anyways and fixed it/quit the race). And I’ve only done a few rides and races (3 I think) this entire summer, so what gives?
