95 laps, 381 Turns

With roads narrowed by high snowbanks, and the thermometer stuck in the teens, many runners are exercising the better part of valor and moving indoors -- and not just for track workouts, but for recovery days, long runs, and more.

Sam Donovan describes a 12-mile run on the 8-lap-to-a-mile Brandeis indoor track. Tyler told me about doing a six-mile run on the 12-lap-to-a-mile "gym" running track at Dartmouth, where they have "clockwise days" and "counter-clockwise days."

But all of that pales when compared to the running of the first "InStep Icebreaker Indoor Marathon" at the Pettit National Ice Center in West Allis, Wisconsin. The race was run last Saturday on an over-sized (> 400m) indoor running track built around an ice-skating rink which kept race-day temperatures to 55 degrees.
