Last Spring I ran a 5K PR at the Mother's Day 5K and figured I'd have a long season of PRs given how little running I'd done before that. Indeed, I had already PRed at the Rivah 10 miler and a couple of weeks later I PRed at the Pineland 25K despite a run-stopping side-stitch. But the summer and especially fall races didn't pan out as expected, which really bothered me. How could my fastest running be in the spring with having run so little during the winter?
Fast forward to today. I ran for the first time the mid-winter classic 10 miler. It's a great course, superbly directed (by Chandra and Blaine), and it was fun to race with lots of friends. Still, I was pretty unimpressed with my time. To compare with other races, I'd have to come up with equivalents, so I used McMillan's calculator to compute my marathon equivalent (left axis) and 5K equivalent (right axis) for all of my road races on certified courses. I've color coded each race by distance.

1. I'm clearly fastest at 5Ks and get less fast with increasing distance
2. My poor races are generally because of either heat or side-stitches. That's not an excuse for today's race
3. I seem to have peaked
4. I've never not PRed in a 5K!
One possible cause of the peak is my aging. So I reanalyzed the data using WAVA age graded tables, which gives you a score, which I suppose could be compared among anyone. It's a little harder to see if the current trend is a peak or just a few bad races. Regardless, this plot really shows an amazingly linear progression (until my last few races that is).
