[Many figures] Awesome: How capable are dogs?

It is already the beginning of spring here, while in the northern United States and Canada it is the season for dog sled races. This is a very interesting and physically demanding sport, one that embodies the harmony between man and nature, and is extremely popular locally. The longest race covers a distance of 1,868 kilometers, requiring a team of 16 dogs to pull one sled, taking 8-12 days to complete the entire course. The endurance and resistance to cold displayed by the dogs is truly breathtaking!
