This is a winter sport that is just beginning to become popular. Based upon dogsledding, ski joring is like dogsledding on skis. You travel on your skis while the sled dogs pull you.
Beginners typically start with one dog and work their way up from there.
Most people are surpised with how strong the dogs are. And they are extremely eager too. If you fall, they'll often drag you a short way before they realize you aren't sliding as easily anymore.
