Great answers. I only did a training program in ERG mode atm, hence my confusion. Good to know I did not buy the extra cassette for nothing :)
Ok, will schedule the FTP test for the weekend. I used to be an IM, but now at best, I'm a Sunday rider with a beer belly. The zones seemed pretty hard at the default level.
Wow IM! That's great, much respect. you obviously know all about training and training zones then, I'll stop ELI5 then!

That was nearly 10 years ago. Never used Zwift before, so quite useful to get some ELI5 for this platform. But indeed, I know about zones, VO2max, etc.
