Organizers of the John Beargrease Sled Dog Marathon on Monday night postponed the annual race until March 10 due to a lack of good snow, the Duluth News Tribune reported.
The race was to have begun Jan. 27.
"It was tough, but the trail is terrible. The rain sealed the deal," race coordinator Pat Olson told the newspaper Tuesday. Organizers said a rough trail made the race unsafe for dogs and mushers.
The annual race has been run since 1980, although it was canceled in 2007 and last year because of poor conditions.
The 400-mile race runs from Duluth along the North Shore of Lake Superior, up the Gunflint Trail and returns to Duluth.
The race is named for the man, who along with his brothers, delivered mail between Two Harbors and Grand Marais between 1879 and 1899, using canoes, horses and boats – and most famously, dog sled.
