The fastest sprinter at the Sydney Olympics will not surpass 37km/h (23 mph)

The world record time for the 100m is about 10sec, which works out to 36km/h, but this is an average speed from a standing start. I don't know how long it takes to reach maximum speed, but when the runner crosses the finish line, he's moving a helluva lot faster than 37km/h. ISTR the fastest human land speed being >=64km/h.
