What was the main differences between balto the movie and the surum run of 1925?

Answer 1

• The sled run to retrieve the medicine was actually a relay. Instead of being the leader of the first team, Balto was the leader of the last team to carry the medicine to Nome. The longest and most hazardous distance was traveled by the team led by Togo.
• The medicine was never driven by the dogs alone, and none of the mushers were incapacitated.
• Balto was never an outcast as shown by the film, but was instead born in a kennel owned by the famous musher Leonhard Seppala, where he was trained until he was deemed fit for pulling a sled as the lead dog. Seppala was also the owner of Togo, whom he personally used to lead his dog team during the relay. Balto was actually used by one of Seppala's workers, Gunnar Kaasen.
• Obviously, Balto is the only animal, and possibly the only character, in the movie who is real.
• Also, Balto was not part wolf. He was a Siberian Husky.
