What is this movie about dogs?

I remember vaguely about this. This person wants to take part in a
dog-sledding race. Then there are people who are also in it and try to
sabotage him e.g cut the rope of the sled But the person emerge as
first anyway. I think there are something about the Northern Lights.
This is small clip of it, intended as a joke.
