I agree the sprint will be pretty tough. Just a data point, the world record from Francois Pervis from a standing start for the 1k in cycling is 56.303 seconds, and his 250m split was 17.671 seconds during that record. Assuming he reached his max speed at 100m and than held on to that speed until the finish, his 100m split was 10.0 seconds. Obviously there are some questionable assumptions in there, but this is a world record holder on an event that is very close to an all out sprint, and these calculations suggest that he was slower than Bolt over the initial 100m. I think a world class track cyclist could do it with a lower ratio on their gear than normal could do it, but a regular Joe most definitely couldn't.
