The Iditarod race is about 1000 miles long, she should finish in less than 2 weeks. And she won't have a single person ask why she brought her dogs on the Trail.
"Karen also enjoys backpacking, and in 1997 she spent six months hiking the Appalachian Trail with her best friend, her dog Kirby. “Kirby is why I am a musher,” says Karen. “I figured if I could have such a bond with one special dog, it would be great to explore the wilderness with 16.”
