Ten world-class sand sculpting teams arrive in the Bay of Fundy in New Brunswick to compete in the ultimate beach showdown.

The best sand sculpting teams in the world must battle the tide and each other, to build underwater inspired creations.

The eight remaining teams are forced to go sky high in an architecture challenge. But sometimes, the bigger they are, the harder they fall.

The seven remaining teams are put under the microscope, as they create teeny tiny items on a massive, macro scale.

The teams must bring to life a fossil from a creature who lived long ago. The challenge may be prehistoric, but the rivalries on the beach are alive and well.

Only five teams remain, and they’re going to have to get in touch with their dark side when they create a spooky, scary sculpture to be revealed at night.

The sculptors are asked to dig deep, as they bring to life a personal memento using emotional carving. But Mother Nature has her own story to tell.

The top four teams are going to have to do double duty in an epic superhero supervillain face-off challenge.

The top three teams must pull off a spectacular mind-bending optical illusion if they want to make it to next week’s final.

In the season finale of Race Against the Tide, the top two teams go head-to-head in an all-out beach battle, for all the glory and the grand prize of $10,000.
