Raced CBR after Thursday's second Pfizer dose. It was fast and (for me) difficult, but I don't think I raced it super well. Not sure if cobwebs or vaccine is to blame, I pretty much just played pack-fill the whole time. I tried getting up towards the pointy end a couple of times but quickly decided it was too much on the legs.
Avg speed 29.4 mph
Avg power 197w, 213w weighted avg according to Strava
So this tells me I was fairly efficient, but also that I should have been able to push way harder. Oh well. I took some gopro footage, mainly for my own review, but if anyone's interested:
Not much interesting except I moved up at about 20 mins in and played around near the front before deciding I didn't want to anymore
