Frozen Bottles

You know it's cold when your water bottles start to freeze in the first 60 minutes.
Tuesday was a tough run along Fire Island from Smith Point to the Moriches Inlet and back, not made any easier by the icy wind blowing spindrift from the northwest; I tried to capture what it was like.
It's surprising how little you notice the cold when you're running, but it does make me wonder how much of a challenge acclimatization is going to be.
