If you learned about the Iditarod when you were in elementary school, you probably thought it was the coolest thing on the planet. If you don't know what it is, the Iditarod is a dog sled race that takes place every year over the course of multiple days, and when I was in elementary school we learned an epic story about how the winner around 10 years ago got a room in an inn with the guy in second place on the last night of the race and then snuck out at around 2 in the morning and woke up his dogs and finished the race before the sun came up. It's truly competitive and requires a lot of training and a connection to your animal, three things that can be found in another winter sport that is growing in popularity.
