In 1925 Seppalia and Togo together made a difficult and dangerous journey across central and northern Alaska to bring diphtheria serum to Nome. With other mushers and 100 dogs they braved minus 30 degree temperatures, ice floes,and 5,000 foot mountain peaks before handing off the cargo to another musher and another sled dog named Balto (who has a celebrated statue in Central Park) for the last part of the trip. Many mushers today consider Balto to be the back-up dog, as Seppalia's team led by Togo covered the longest and most hazardous leg of the journey. They made a round trip of 365 miles.
