The 2012 Iditarod enters the middle of its first week on Tuesday, and the teams are still just easing into the two-week journey. The stretches involving strategy and planning will come, of course, but the dogs and their mushers typically take the first few days of the race to get their bearings.
The Iditarod map route shows the route from Anchorage to Nome; for reference, most of the lead teams were leaving Rohn, the seventh checkpoint since Anchorage, late Monday night Eastern time. The current Iditarod leaderboard can provide more information on just which teams those are.
As for the Iditarod weather conditions, as one would expect for Alaska in March, it's cold. Temperatures were in the teens with light snow in Skwentna, just before Nome on the route, and dipped into single digits in Nikolai, site of the first checkpoint after Rohn, with some severe weather alerts. The race thus far has been mostly without inclement weather, but that could obviously change.
