Why does it still feel like winter?

It seemed like a nice enough day to run, well actually they all do in the end but this year has been hell for the weather. Today the temperature was pleasant, 12C and mostly clear. Due in part to the 30knot winds blowing off the ocean. Brutal. I laced up and headed out, determined to make a go of it. At 4k, I realized I had underdressed but was running fast enough to try to ignore the wind. No such luck. At 8.5k, my right knee started to hurt, not inside but on the outside. Kinda weird as I have not had any joint problems thus far. I walked and ran for the next couple of km till it went away somewhat. I finished strong but almost completely undone by the wind. It was rotten out there. I am really hoping for some nice weather and several months of it. 1:13:33 ~ 14.33 km, 5:07 per km.
