Most treadmills max out at 10 mph or so. Maybe 12. I have run a 2:44 marathon and at my best I would have been able to keep up with them for about .5 miles (based on my 800 meter time of 2:10). Very few people can hit that pace without damaging something unless they have seriously trained.

Agree on the incredible part. I have seen elites race in person at the 2008 Olympic trials and it is unreal how smooth and fast they are.
