ANCHORAGE, Alaska (AP) – Four-time Iditarod champion Susan Butcher died Saturday in a Seattle hospital of complications from a recent bone marrow transplant, a hospital spokeswoman said. She was 51.

Butcher, who grew up in Cambridge, Mass., dominated the 1,100-mile sled dog race from Anchorage to Nome in the late 1980s. In 1986, she became the second woman to win the grueling race. She added victories in 1987, ’88 and ’90 and finished in the top four through 1993.

“What she did is brought this race to an audience that had never been aware of it before simply because of her personality,” Iditarod spokesman Chas St. George said.

In 1979, Butcher helped drive the first sled-dog team to the 20,320-foot summit of Mount McKinley, the highest peak in North America.

Butcher ran her last Iditarod in 1994 when she decided to have children. She has two daughters, Tekla and Chisana, with her husband, attorney and musher David Monson.

Three years ago, when she was considering a comeback, doctors found Butcher had, a rare disease that causes the bone marrow to produce excess blood.

Butcher planned to compete in a 300-mile race last winter, but was unable to compete after she was diagnosed with leukemia in early December.

“Now my goal is to try and stay alive and fight leukemia,” she told The Associated Press. “No questions asked, that’s what I am going to do.”

During her chemo treatments, Butcher daydreamed about land in the White Mountains she and her husband bought last fall. They planned to build a bigger cabin on the land that comes with 300 miles of groomed trails – perfect for mushing dogs – right out the back door.

“I got the cutest, lovingest group of well-trained females. They are easy to handle and I just enjoy them,” she said. “They will be waiting for me.”
