Today: very windy again. Headwind for first 3.5km; tailwind for next ~5km, then headwind for last 1.5km. Ughhhhhh....it wasn't that cold but with the wind it felt so cold! It was 2.2C (36F) but 19kph (12mph) steady wind with higher gusts. So I was slow to start, but with the 3 fast segments (all done with the tailwind for obvious reasons) of 2:56, 2:55, 2:51, my overall time was still decent despite the wind. I did 1:03:57 for 6:24/km with ave HR 142 and max 159 during the bursts.
I felt good during and not really very tired at all. Afterward, my legs feel fine :). Yay! Surprised that I felt so decent the day after a hard 8K fartlek, but I guess I'm getting better :) :) :). Happy Happy Happy!
