I agree, but I seem to have a mental block where running is concerned.  I could play midfielder in soccer which causes you to run non-stop for an hour while chasing a ball, but you tell me to run on a track or a trail and I think I'm going to die in about 15 seconds.  I will never be a runner.

On the other hand I dash everywhere.  I dash to the door.  I dash to the printer.  I dash downstairs and back upstairs.  I move a lot and fast, but don't tell me to run.
