Togo and his musher Leonhard Seppala are the real heros of the Nome serum run. They ran the longest and hardest part of the run. They traveled over 170 miles in 3 days (and another 180 to return), including over the open ice of Norton Sound. After the run, Togo could never run again. His remains are in Wasilla, AK at the sled dog museum. Balto and Gunner are far less interesting if you ask me.
