Big weekend in the motor sports world, and it's happening here in Maine.

Sunday River Ski Resort is once again playing host to one of the marquee events for the Red Bull Signature Series. The Red Bull Frozen Rush featuring 900-horsepower Pro4 trucks starts Friday and runs through Sunday.

The event throws racers a curve-ball with the course being covered in snow, rather than the usual dirt, sand and gravel tracks.

Last year Ricky Johnson won the event. He'll be back again this year to defend his title.

A full-length broadcast of Red Bull Frozen Rush will air Sunday, March 1 at 2PM (Eastern) on NBC.

The event will be live streamed on Red Bull TV tomorrow at 12:30PM via the Red Bull TV player at RedBull.com/frozenrush.
