Today was a cold day, temperature between -16 and -21 °C. It was good to be outside. I did some more cross-country skiing, which provides excellent exercise. I wore the Polar heart-rate monitor, which told that I used 800 kcal in one hour of skiing.

Here are three photographs from today. Sunny and bright, cold and blue.
