OK racing question...
I want to sign up for a race and it gives me category options:
A: 4.0-5.0w/kg
B: 3.0-4.0w/kg
Do I select my category based on my w/kg @ FTP? Or based on what I expect to maintain for the race? If I go by FTP, I would need to select A as my FTP is about 4.4w/kg. But if it's a long race I am not going to maintain over 4w/kg for say a 100km race (I am talking about selecting the category in the Zwift race event signup page, not the ZwiftPower category)
Also I don't quite understand how ZwiftPower uses 95% of whatever 20 minute power you did in your last few races. It's not like everyone is FTP-testing in every race. If you are doing a 50-100km race you are not racing at FTP the whole time obviously. So your best 20 minute power in that race will be much lower than your FTP.
With 4.4 Wkg FTP, you should definitely start in cat. A. Not even close to cat B. level imo...
Regarding the races in cat A. typically the start is not very hard (you should be able to make the first group with ~400W for first 10-30 seconds and then some bursts) The races will only truly open up on any incline, and are determined by 1-5 min power ... don't be a hero in between hills and just follow wheels, you're not going to ride of the front of the A-cat on a flat road. For very long races the avg. power is obviously lower for everyone ... could very well be that you don't even need 4Wkg to finish with/ close to the 1st group in such long races; just be prepared to get dropped in final part of the race ... that's reality for most non-elites
Regarding your 2nd remark; ZP nowadays takes 95% of 20min power of your 3
best performances of the last 3 months in both races AND events.
