Who are the best in 300 meters punchy-sprint?

Re:

^^ have you seen Lobato's acceleration compared to Degenkolb.in that Dubai stage

Yeah, Lobato seemed to start his move much later than Degenkolb - so probably was going a bit easier at the start of the climb and then did a full out effort in the last 20 seconds or so, almost like a flat out sprint, so his top speed would have been higher. Degenkolb measured his effort to perfection though - he barely lost speed until the line, and then was on the floor straight after completely spent!

Re: Re:

So many different factors involved like speed into the climb and wind direction but what speed would they be able to put out on a 15% climb at maximum anaerobic effort, after the initial slow down and assuming no tailwind.

Kittel - at 86kg and with an estimated 1 min power of around 11w/kg would average 946 watts. Which equates to 22.4km/h at 15%.

Rodriguez - at 58kg an with an esitmated 1 min power also of around 11w/kg would average 638 watts. That equates to 21.6km/h at 15%.

Degenkolb - at 79kg, with probably a slightly higher 1 min power - let's say 11.4 w/kg - would average 900 watts. That equates to 23.1km/h.

Valverde - at roughly 62kg, probably has w/kg of around 11.5 for one minute (about as high as it gets). He would average 710 watts - which would be about 22.6km/h.

That's all with no wind and with a bike weighing 7kg.

These figures pretty much support what we saw in that Dubai stage. Degenkolb storming to victory on raw power; Valverde putting in a decent performance, and Rodriguez further back.

My thoughts are that I dont think Kittel could sustain a minute at full power, how long in a typical sprint is he on the front out in the wind, 10 seconds?

Yeah, he's probably only at the front for 10 seconds. But the figures above are an estimate of the power they can sustain for a minute, not full power. At full power, Kittel can produce around 1,800 watts, with a peak of close to 2,000 watts. That would give a speed over 35km/h even on a 15% gradient (assuming they started at the same speed).

Here's a video of him training fairly steep uphill sprints, going flat out. Huge power output.

Re:

Gilbert can't do **** at 12% unless we're talking about Gilbert of 2011, he could do anything but that guy is gone forever.

Edit: wait why 300 meters? That's way too short, how much speed to they have before that, 50, 60km? or 30km? 300meters is ridiculous to use.

How did he manage to Win Amstel Gold last year then?

He'd be my pick on anything over 10% but probably needs to be longer than 300m

And to be fair, he does appear to over-take Degenkolb
