🦠 The Diphtheria Crisis in Nome
In January 1925, a deadly diphtheria outbreak threatened the remote town of Nome, Alaska. The town had about 1,400 people, including many Indigenous Alaskans who were particularly vulnerable to the disease. The only doctor, Dr. Curtis Welch, diagnosed diphtheria in several children, and without an antitoxin serum, a major epidemic loomed.
The only available antitoxin serum was over 1,000 miles away in Anchorage, and the situation became desperate. Due to blizzard conditions, -50°F (-46°C) temperatures, and nearly zero visibility, airplanes couldn’t fly. Ships were blocked by sea ice. There was only one option left: dog sled relay.

🐾 The Serum Run Begins
The plan was to transport the serum by rail from Anchorage to Nenana (674 miles), and then have a relay of dog sled teams cover the remaining 674 miles to Nome. This mission was led by 20 mushers and over 150 sled dogs.
The teams would pass the serum like a baton from one to the next, racing against time and nature.

🐺 The True Hero: Togo
The most heroic leg of the relay was run by Leonhard Seppala, a seasoned musher, and his lead dog Togo. They covered 260 miles (418 km) — the longest and most dangerous section — across the frozen Norton Sound, where one wrong step meant drowning in icy water.
Togo led his team through gale-force winds, blizzards, and breaking ice, showing unmatched intelligence, stamina, and courage. At one point, Togo helped the team survive after they became stranded on an ice floe, dragging the sled back to the main ice sheet.
Seppala and Togo’s run is considered one of the greatest feats of endurance in sled dog history.

🐕 Balto: The Final Sprint
Gunnar Kaasen and his lead dog Balto were part of the final leg. They ran 55 miles (89 km) and delivered the serum to Nome on February 2, 1925, completing the journey in just over five days — a miraculous time for such a brutal trek.
Though Balto was less experienced than Togo, he successfully guided the team through the final white-out blizzard and brought the serum to safety.
Because Balto was on the final leg, he and Kaasen received the most publicity, with Balto becoming a national hero. In December 1925, a statue of Balto was unveiled in Central Park, New York, which still stands today, honoring all the sled dogs of the serum run.

🏅 Legacy of Togo and Balto
Balto was celebrated in newspapers, on radio, and even in film. His body was preserved and is displayed at the Cleveland Museum of Natural History.
Togo, however, was largely overlooked at the time, despite doing the most grueling work.
In recent years, Togo has finally received recognition. In 2019, Disney released the movie “Togo”, starring Willem Dafoe as Leonhard Seppala, correcting the record and honoring the dog who ran into the heart of danger to save lives.

📜 Conclusion
The 1925 serum run to Nome is a remarkable tale of human and animal endurance. While Balto symbolized the success of the mission and became a popular hero, it was Togo who truly demonstrated unmatched heroism over the harshest part of the journey.
Both dogs — and all the teams who took part — remain legends of Alaska’s snowy wilderness.
