Tomorrow CBS is set to air the one-hour preview show “Road to World's Toughest Mudder” at 1:30 pm eastern time. The show will highlight the journey of some of the topic contenders from the 2018 World's Toughest Mudder. The full special will air on December 15, 2018, at 12:30 pm eastern time. With a new venue this year and record cold temperatures, World's Toughest Mudder was anything but ordinary.

The action-packed race features competitors from various disciplines, providing a true battle among all participants. Viewers will witness these world-class athletes test their strength, agility, and speed over a five-mile course featuring 26 obstacles, 10 of which are new and updated Tough Mudder obstacles. The man and woman with the most completed laps of the daunting course after 24 hours are declared the winners.

Highlighting the field is 3-time Men’s Champion Ryan Atkins, who will be competing in the team event this year, alongside his wife, Lindsay Webster, Ryan Woods, and Brian Gowiski. On the men’s side, 2016 Champion Trevor Cichosz and long-time Tough Mudder competitor Kristopher Mendoza will be battling it out for the top spot on the podium, as well as military veteran, Dancing with the Stars competitor and adaptive athlete, Noah Galloway. The elite women’s field will feature another epic duel between last year’s champion, Rea Kolbl, and last year’s runner-up, Allison Tai.

In addition to watching the athletes show their skills, CBS will give viewers a sneak peek of the new and updated obstacles for the 2019 Tough Mudder season, which debuted for the first time at World’s Toughest Mudder.
