The Salsa Oremageddon mountain bike races roll Oct. 10 near Crosby, Minn.

The inaugural event takes place amid the increasing popular Cuyuna Lakes moutain biking trail system.

"In working with the Minnesota Department of Natural Resources over the past four years, we were able to create a one-of-a-kind event, racecourse and opportunity for cyclists throughout the entire Upper Midwest to enjoy," said Aaron Hautala, Cuyuna Lakes Mountain Bike Crew chief.

Hautala said there are 350 registrants for the races (50, 25 and 12 miles and each with varying levels of difficulty). There was "overwhelming demand." All the money raised from the event will go toward the mission of the bike crew: maintenance and expansion of the Cuyuna mountain bike trails, Hautala said.
