They run odd years for southern and even years for northern.

2. they run the northern route in odd years, and run the southern route in even years
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.
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).
on the odd years they go the the southern route.they change every other year
In even years, the Iditarod follows the Northern route. The halfway point is between Cripple and Ruby, closer to Ruby.
It is a dogsled race that takes place in Alaska. There is a ceremonial start in Anchorage Alaska, however, due to the urban nature of the area, after the ceremony the race moves to Willow Alaska, about 80 miles north of Anchorage, and goes from Willow to Nome Alaska.
The Iditarod from 2018 has run for 45 years
During the early years of the Iditarod Race, the mushers only traveled the northern trail. After several years, the Iditarod Board of Directors realized that the smaller villages were being heavily impacted by the race coming through their village year after year. It was decided to use both sections of the trail. This decision had a three fold effect. The northern villages of Ruby, Galena and Nulato only had to deal with the large group of mushers, press and volunteers every other year. The second effect was that the race was able to pass through the actual ghost town of Iditarod. Lastly, the villages of Shageluk, Anvik and Grayling were able to participate in the race. iditarod.com/learn/iditarodtrail.html
