My best year as a cat 2 I did 282w for 55m at training camp. I think I got a little fitter that year, so I maaay have been able to pull off a 290w on a better day. At 66kg, I didn't even beat all our cat 3's up the climb at that power. I think I was 6th fastest on the day or something like that? Best time was about 7 minutes faster. None of the guys that went faster than me were lighter than me either, so I imagine they were all over 300w. So, I would say it's not super common, but not rare either. I think we had ~40 guys doing the climb ranging from cat 1 to cat 5
The 300w FTP is something I've been chasing for years
