This is fun!
Conveniently for comparison, 2006 and 2016 are bookends to my time running M21.
2006 USOF Ranking Score: 67.1 Red
2016 OUSA Ranking Score: 83.4 Red
Also, I recently discovered that my only other AP log entry of one lap around Green Lake is from 2006.
The comparison is a bit less fun for me as this whole grad school thing is doing a great job of accelerating the decline that would naturally come from age. Interestingly, the 2006 Pere Marquette would have been my first time under an hour if the snow hadn't been so deep. Since then, I've been comfortably under except in three years when conditions were atrocious. I rather expect that this is the year I fail due to fitness. We'll find out in three days.
