I didn't realize there were several indoor marathons to speak of. Articles are here<http://www.jsonline.com/blogs/lifestyle/137666713.html> and here<http://www.jsonline.com/blogs/lifestyle/137863048.html> for the Icebreaker Marathon Gold Medal Challenge.

Call it a form of active hibernation.

More than 800 runners from 21 states will tuck themselves into the Pettit National Ice Center and race this weekend in the fourth annual Icebreaker Indoor Marathon.

In the cool confines of the ice center, dashers and plodders will turn thousands of laps in a 5K, half marathon, marathon and marathon relay. The truly committed will compete in the Slendertone Gold Medal Challenge, combining the half-marathon on Saturday and full marathon on Sunday.

For them, the weekend will be spent turning left, through 143.1 laps on the 443-meter track that circles the ice oval.

Inspired by the Zoom! Yah! Yah! Indoor marathon at St. Olaf College in Northfield, Minn., Chris Ponteri created the Icebreaker in 2009.

It took off.
