Now THAT was cold!

Today I ran a 10K tempo with Ken. It wasn't until I turned on the radio on my way home that I realized it was -27C with the wind chill! It took forever for my feet to thaw out during the run and it felt like I had two icicles for legs. I managed to do the run in under a 5K/min pace but it felt like I was running faster. Perhaps my brain was starting to freeze?
