The Iditarod is ran on the northern route on even years. The northern route has more villages along it than the southern route ran on odd years.
In even years, the Iditarod follows the Northern route. The halfway point is between Cripple and Ruby, closer to Ruby.
they maned the iditarod after a ghost town the race route passes on the northern route, which they run in odd years, rather they run the southern route in even years.
2. they run the northern route in odd years, and run the southern route in even years
There are 26 checkpoints on each route in the Iditarod. The southern route is taken on odd numbered years(such as this year,2013) and the northern route is taken on even numbered years. I'm not able to give the exact information of where each checkpoint is on both northern and southern routes, but somewhere else on wikianswers(this website).
They run odd years for southern and even years for northern.
I decide the route
At this point in the race (official start day), the 2012 Iditarod is following the northern route, as it does every even-numbered year. Though some route changes have been made (for instance, removing then re-instituting the Happy River Steps), it is unlikely that the race officials would opt for the southern route. With near-record snowfall along the northern route (and more to come), the southern route would likely be an easier run. That said, the villages along the trail depend on the every-other-year boost to the local economy, and the infrastructure is already in place to run the northern route.
