DENVER - A rambling storm dropped as much a foot of snow in the mountains and shed rain at lower elevations Sunday, slowing marathon runners, wetting baseball fans and jump-starting the ski season.

The snow caused some fender-benders but no injuries along Interstate 70 through the mountains, State Patrol Master Trooper Ron Watkins said.

Freezing rain made the Denver Marathon even tougher as participants ran through neighborhood streets.

"You cannot move very fast. It was tough," said winner Jonathan Ndambuki of Kenya. "I even started freezing a little."

Fans at the Colorado Rockies' playoff series against the Arizona Diamondbacks cheered under drizzle.

Keystone Resort said it would begin snowmaking Sunday night, and Breckenridge Ski Resort planned to start blasting snow guns at the end of the week. Both resorts plan to open Nov. 9.
