MARQUETTE - As the Upper Peninsula Sled Dog Association prepares for the 25th consecutive running of the U.P. 200, the organization has announced changes to the 2014 races. The U.P. 200, Midnight Run and Jack Pine 30 will return to the central U.P. Feb. 14-16. This is a date change that moves the races one week earlier. The new date will allow more mushers to enter and spaces several major races two weeks apart.
