I'm definitely getting faster. I ran four miles last night, doing a run/walk plan of 30 seconds per half mile. Over all I came in under ten minutes a mile, and for the running sections, I ranged from 9:45 to 9:05, according to my Garmin.
At work, I interviewed a prospective employee who ran middle distances in college. His PR for the marathon is 2:32. He said he could get me down to a 3:30.
Of course, folks will say anything for a good job, won't they?
