Average pace

Upon the suggestion of a friend, I decided to figure my average running pace. Unsurprisingly, it has increased (though not steadily) since I resumed running in 2006 (after the 12-year hiatus following my severe 1993 accident.) This was fairly easy to figure, as I keep ongoing cumulative records of elapsed time and mileage ... so, using these, I was able to determine that in 2006, my average pace per mile was 8:58 (on a total of 732.7 miles); in 2007 my pace fell off considerably, and was 11:23 (for 932.2 miles); in 2008, the pace was 11:41 (for 1181.7 miles); in 2009, the pace improved considerably and was 9:28 (for 1000.2 miles); last year, my pace was 10:57 (for 724.7 miles); and this year so far, my average running pace is 11:30 (for 316.1 miles).
As this same good friend and fellow runner who is just a year younger than I reminds me, "You're no spring chicken!" (A line with significance to us, because early this year he was told this about himself, and he said that for the first time -- now that we are both in our early fifties -- it bothered him! :) And he is very clearly absolutely right about me. Rather than getting discouraged about the slowing down, however, I am just going to keep doing the best I can, and figure it's better than giving it up altogether.
