Iditarod 2012 Update: Day Five

Day five is underway, and teams are already making their way toward Cripple, the tenth checkpoint on this year's Iditarod trail.

Musher Aily Zirkle, the woman who has dominated this year's race so far, has slipped to fourth place, with Jim Lanier now in the lead. John Baker has also dropped from second to seventh place, as mushers Trent Herbst and Mitch Seavey battle it out for second place.

Surprisingly, only one musher has scratched so far, which is rare this late in the race. Rookie Silvia Furtwängler threw in the towel last night after arriving at the Nikolai checkpoint due to concerns about her health.
