MINNEAPOLIS (AP) — Thirty mushers and 420 dogs will hit the trail Sunday in a rebooted John Beargrease Sled Dog Marathon with new, fan-friendly features that organizers hope will help the Minnesota tradition recapture some of its former glory.

The 30th running of the Beargrease, which once rivaled Alaska’s famed Iditarod for prestige and prize money, boasts technology upgrades and more prize money. The starting line also was moved from an inland site north of the city to a more convenient site in Duluth, where organizers hope thousands of fans will gather for Sunday’s start.

People who don’t want to brave temperatures that are expected to be around zero degrees can watch the start live via streaming video. Also this year the sleds will carry GPS devices so fans can track the teams on the 374-mile course up the North Shore of Lake Superior to Gunflint Lake and back for a finish Wednesday.

The Beargrease is being staged this year by a new management team, taking over for a volunteer crew that had run out of money, ideas and energy. In fact, the volunteers announced last October they were scrapping the 2014 race, spurring the new team to step in and quickly cancel the cancellation. The boosters also lured back a major sponsor, Black Bear Casino Resort, which put up a $35,000 purse.

“Our first mission was to just make sure the race didn’t go away,” said Jason Rice, the race’s president. “We’ve done more than that — a lot more than that.”

Rice and other organizers are particularly excited about the GPS tracking system. He said they can’t guarantee the system will run perfectly, but it should make it easier to follow the action via computers and mobile devices as the teams head into the backwoods.
