Today, December 15, 2009, less than a week before it is officially winter, I walked out my front door at 6:00 p.m. in shorts and a short sleeve shirt for a 7 mile run. The temperature was 61 degrees F (16C). I wore a pair of Brooks Adrenaline 9's for the last time. At the end of the run, they'd reached 499 miles, time to be retired. The graph shows the number of times I ran the various distances in these shoes. There were 62 total runs covering most distances from 1 to 26. It looks like my fave distance to run with these shoes, the mode, was 4 miles, the median is 7 miles and the mean is 8 miles.
I started wearing these shoes on February 24, 2009 for a 3 mile run around the neighborhood. My pace that day was a nice and easy 9:25. This was when I was still in the middle of rehab for the IT Band Seize Up suffered at the St. Jude Marathon nearly 3 months before. Tonight's pace for the easy 7 miles was 9:05.
I obviously used these shoes to train for a marathon as evidenced by the nice progression of at least one run at 14, 16, 18, 20 and 22 miles, culminating with that nice 26(.2) there at the end. When the marathon rolled around, the Heart of America in Columbia, Missouri, these shoes already had 355 miles on them. By the time I realized it, it was too late to start out on a new pair. The old blue GTS9's served me well that day. Since then they've been in the rotation mostly used for 5 and 6 milers. Today, 42 weeks to the day after their inaugural run, they are getting relegated to the garage with all the other pairs of 500 mile shoes.
This makes the fourth pair of shoes I've retired in 2009. There are two others in the rotation that won't make it far into 2010 before joining the stack in the garage; a pair of red Brooks Trance 6 with 474 miles and a pair of red Trance 7 with 437 miles. The fourth pair in the current rotation is an Adrenaline 8 with a mere 185 miles and there's a brand new pair of Adrenalines waiting in the closet for their turn to join the rotation.
Do you think I know too much about my shoes?
