Cat 1's and 2's often pull 1600-1800 watts out of the turns in crits. But you can watch those number drop ever lap until 800 watts in a sprint at the end of the race is good. I can only imagine what Pro's are doing.. I have to ride 4 days a week of my power in the climbs suffers. and that is probably only 200 watts.

Mmmm. No. Not unless its a bunch of super-strong Clydesdale CAT 1/2s. Sagan is doing 1200-1500 watts in a flat sprint.

Here's an analysis of power data from Mathieu van der Poel at Strade Bianche:

In his winning attack to drop Alaphilippe with about 500 m to go, van der Poel
hit a peak of 1362 W, and held 1146 W for 15 seconds.
Inform us all how you know what Sagan is generating? Imagination? They have a video somewhere of a crit with a power meter overlay that shows a Cat 1 early in the race coming out of corners and generating 1800 watts and as the race goes on that drops down until the final sprint he can hold only 1,300 watts. But you are palsy-walsy with Peter Sagan and know everything about him. Even when he went into breakaways and was climbing with real climbers.

Sagan's power numbers are all over the internet. You do the search. And if you have video of Cat 1/2s are producing 1800 watts, please provide us with a link. That number may be attainable by a strong road Cat 1/2, but for maybe a second -- and probably not coming out of a corner. 1300 watts for a 5-10 second road sprint, assuming the usual death-camp survivor body type, is huge. Those are not amateur numbers -- on the road. Some good Cat 1 track sprinters can probably do 1800 watts for more than a second or two.

BTW, I do know some guys who rode with Peter. He has a place in Park City, and some of my son's friends ran into him on a MTB ride, and he went along with them. He's really friendly guy, or so I'm told.

I've been trying to find that video and I can't find any of these crits anything like the one I was talking about. The highest power readings I saw was only (only!) 1200 watts. Also these crits were almost all on fairgrounds or something that had mostly one direction turns. The one that I saw before with the high power readings was a complicated course with a lot of lefts and rights. This makes me wonder if it was a Belgium crit that I saw. But the little narration there was was in English.

Also, in this other crit video the speeds were all hell and gone faster.
