I used to compete in the 100 meter dash in college. Did you run track?
No, I did not. Did you enjoy it?
Yes, I wanted to be the fastest man in the world.
I admit I don't have a lot of knowledge when it comes to competitive running, however I did enjoy watching Usain Bolt run. 
Yes, he was awesome. I can't believe he held records for the 100 and 200 meter.
Yes, I still remember the first time I saw him run. He knew he had it and slowed down to celebrate before he made it past the finish line and still won by a huge stretch. 
Many he is widely consider him to be the greatest sprinter of all time.
That does not surprise me. Do you still run? 
Yes I'm slowly working on breaking the 10 second barrier
