DULUTH (AP) - Duluth is forging ahead with its plan to become a premier mountain biking city.

The Spirit Mountain ski area plans to add two more downhill mountain bike trails to add to the two it already has.

Cyclists of Gitchee Gumee Shores plans to build nine miles of trails in the Mission Creek area and add 3 1/2 miles to the 5 1/2 miles already in place in the Lester-Amity Park system. The club is also getting permits for a 100-mile trail across Duluth from Mission Creek to Lester Park

Starting May 23, Spirit Mountain will begin operating a lift for bikers and other users from Thursdays through Sundays, taking people and bikes from the new chalet at the base of the ski hill to the top.
