i did my club's group ride yesterday evening, joined in the B group because a) it's rest week and b) I know my power profile is too one dimensional to keep up on the hills. Even with the B group I was kind of in between the initial group of B+ guys and what I'd call B- guys on the route's main climb that generally takes 8ish mins, I averaged 289w (4.1w/kg which is my threshold) for 8.5mins. I did a good amount of pulling initially, though, and for the first hour had an NP of 260 (0.9 IF) so it was a good time.
