I'd almost prefer running when it was -20 C. It was so windy I had to be careful of my footing and balance, and it was raw running into the wind.
Ran and walked 5 K exactly in 41:32.
5 min warm up
4 x 5r 2w.
8 min cool down
This all started at 5:30 or so, since Linda didn't need to be dropped off at work. I started with a twinge in my left knee, but it went away during the first run segment. The only time my calf complained was during a faster segment crossing a road in between traffic. Overall I kept it slow, with fairly low heart rate out of consideration for my tired legs, and with a thought towards the spin session tonight.
