Iditarod

My class and I are doing Iditarod. Iditarod is a app or you can go on the internet. There are mushers. Mushers are people who do dog sledding. There are 2 weeks the mushers have to go to the finish line. There are checkpoints and volunteers to see if the mushers are ok. The checkpoints stop the mushers time and then the mushers rest. The race starts in 1 days! You can also see their scores and what place they were in. Have you ever known about mushers?
