This was one heavyweight race.

An epic video clip shows three sumo wrestlers — at an average weight of 418 pounds each — sprinting down a track in Japan.

The “heated battle” was shot during a break from practice and was spotlighted in a tweet sent out by a wrestler named Ishiura.

The plus-sized included Amakaze, Kaiho and Takatenshu — who are all touring the region ahead of a tournament on Nov. 8.

The highlight of the footage– a huge hit in Japan– comes at the very end, when one of the butterball’s “mawashi” — a 30-foot-long belt that sumo wrestlers traditionally wear — begins to slide off just as he reaches the finish line.
