It's something I've wanted to see on my stopwatch since I started running, almost 3 months ago. When I ran my first 3 consecutive miles, I was at about 11:30-11:40 per mile. Today, I averaged 10:21 over 5 miles, with my personal record for a mile at 10:00! I finally am seeing some seconds shave off my time. Feels SO good. I really REALLY would like to get down under 10, if I'm shooting for the stars I'd like to get to a 9 minute mile someday.
Today I used my own watch and tried to keep track of my splits (which I just recently figured out what that even meant!) against my nike+ sensor. My mileage seems to be accurate on the Nike sensor, but the time seems a tad slow compared to my Timex Ironman watch. I finally figured out how to work the split timer and how to view it...which if kind of fun. My nike sensor only tells me my average, not the time for each mile, so I liked being able to see which miles I ran at what pace. My first mile was the fastest, but the rest were pretty consistent between 10:10 and 10:20 per mile. Still, my best run yet, I think.
