We started a new club at work. It is called the -20 club. It began with a group that decided to walk outside in T-shirts for 5 minutes, when the Wind Chill was less than -20°C (-4°F). I agreed to join the club, on the condition that they would also do it barefoot. I received a few chuckles but they actually agreed.
Today was our first barefoot walk/run at -20. Next time I need to get photos!
