I did a ramp test in august and then one in september. I put my FTP down a little bit after i was feeling overtrained/ sick for three weeks leading up to the challenge. I turned it slightly up again last week so its almost near my september FTP. I may need to do a ramp test maybe on Sunday. That being said, i think i do my intervals generally on the higher side of the target (+ 10-15 watts) so maybe i should just put my september ftp in TP/Zwift again…
