The first three days of the 2017 CrossFit Games are in the books. CBS Sports will have final-day coverage Sunday with free live streaming from Madison, Wisconsin. Fans worldwide can watch it all online.

A highlight show wrapping up the Games will air Aug. 19 at 1 p.m. ET. 

"The CrossFit Games has gained two powerful and enthusiastic partners in CBS and Facebook," said Justin Bergh, general manager of the Games. "Our community has the respect and support of the largest social-media network in the world and the most watched television network in the world. Both understood how important it is that we craft a unique coverage plan that meets the needs of our global community. This begins with the Games in Madison, but they are both committed to raising the bar for fans, athletes and affiliates year-round."

CrossFit enthusiasts don't need to be told anything about the intensity of these competitions. They take some of the strongest people from across the world and showcase not only their intensity, but also their ingenuity. CrossFit workouts are known for their difficulty, but CrossFit gyms are also known for their creativity.
