I turned on Strava this time, to see how much I've lost from years past. Nowhere near any PR's but I can't complain too much since the long uninterrupted segment is right in around my other 2nd place times. Overall it still seems like I'm slipping although the 19.2 mph total doesn't seem that bad. (edited I found the likely culprit today: tires low at 50 psi - sometimes it's sloppiness not physical failing ...)

This by the way is my favorite part of strava, just a graph of times you've had on the particular segment.
