If you really want, I can use quicktime and do a frame by frame calculation.
Yes, please do that. Using basic math is a lot easier however.

Certainly, that's a given. We don't get to choose our bikes or gearing. You'll notice we are wearing regular tennis shoes and street clothing and are not clipped in. Being several beers in probably doesn't help the speed either.

Also, you can see your speed in the top right corner, you appear to average 82 km/h. Your total time to 500 meters was 21+ seconds, which confirms your average speed. Your max appears to be around 84 km/h. At these speeds, in a reasonable track gearing of around 94 inches your cadence would be around 190-200. In order to hit 250rpm your speed would need to be around 110 km/h. Which we can clearly see, it is not. The gearing would have to be significantly lower for your estimate to be true.
I can post up the math later if you're interested.
You guys are hilarious. Why are you so mad?
Perhaps the red time was averaging 82 but i'm in blue. If you look at the video i'm clearly hitting 90's and let up a few seconds before the end.
Go look up the results and look at the fastest times:
I'm hitting 18's over 500m on a 47x15
gear; tell me what the cadence is for that. Yes, and please post the math.
