What better way to ring in the new year than to relive the competition of the world's fittest?

Vermont's Mat Fraser and Olympic weightlifter Tia-Clair Toomey captured the men's and women's titles at the 2017 Reebok CrossFit Games in August, and CBS Sports Network dove deeper into the 11-year-old challenge with this fall's "Fittest on Earth," an eight-episode behind-the-scenes look at what made 2017's world-class athletes.

On New Year's Day, you'll have the opportunity to catch up on all of it -- or soak it in again -- thanks to an all-day marathon of CrossFit Games action, complete with eight days' worth of men's and women's competitions.
