Career
Swenson competed in the Iditarod for the first time in 1976, placing 12th. The next year, he beat Jerry Riley by just 4 minutes and 52 seconds, and became known for close finishes. He was awarded Sportsmanship awards in 1983 and 1996, and the Leonhard Seppala Humanitarian award for dog care twice, in 1992 and 2004.
The most controversial finish in the history of the Iditarod is his 1978 loss to Dick Mackey.
But Mackey had more dogs and a longer harness, and the nose of his lead dog crossed the finish line in 14 days, 18 hours, 52 minutes, and 24 seconds, one second ahead of the nose of Swenson"s lead dog. Swenson moved to Alaska in 1973 to run sled dogs.
He lived first in Eureka, then moved to Two Rivers in the late 1980s. He has been a fur trapper, gold prospector, and is currently a kennel owner.
He also enjoys woodworking and is the father of three children.
As of 2012, he has stopped competing in the Iditarod.
