The annual event has been canceled because of poor trail conditions in the Moosehead Lake area.
Race organizers said the recent warmer weather and rain have created trail conditions that aren't safe for the dogs and mushers.
They said they're heartbroken and disappointed, but they wouldn't feel right sending out the teams under the current conditions.
The event usually draws about a dozen teams of mushers from all over.
