What is the name of the famous long-distance sled dog race in Alaska?

The story behind the answer

Iditarod is correct because the Iditarod Trail Sled Dog Race is Alaska’s iconic long-distance mushing event, running roughly 1,000 miles from Anchorage (ceremonial start) to Nome across mountains, sea ice, and subzero winds. Teams of Alaskan huskies and their mushers navigate checkpoints with strict veterinary care and mandatory rest, testing endurance and teamwork.

The race honors the historic 1925 “Serum Run” that relayed diphtheria antitoxin to Nome along parts of the same trail, once used for mail and gold-rush travel. Memory tip: “I did a road… to Nome” sounds like Iditarod, the road-like trail across Alaska. The other options—Denali Dash, Nome Run
