U.S. dogsled race. It is held each March and run over a route between Anchorage and Nome, Alaska. It originated in 1967 as a race 56 mi (90 km) long, but by 1973 it had evolved into the current race, a 1,152-mi (1,855-km) trek roughly tracing an old mail route established in 1910. The race also commemorates an emergency mission to get medical supplies to Nome during a diphtheria epidemic in 1925. It typically takes 9-14 days to complete the race. See also dogsled racing
