I've never actually timed myself. I have the fastest sprint out of anyone I know, comes in handy playing sports.
I also run for a little more then a kilometer every morning when school is open. Any time I'm up real early and don't have school I go for a run around the block with the dog. But like I said I've never timed myself.
When we used to run laps every now and then in gym my friends and I never actually ran much. More or less walked around talking the entire time. This was like 3 years ago though so. :P
