The National Pro Grid League (NPGL) was a professional athletics organization consisting of mixed-gender teams that operated from 2014 through 2016.

The NPGL refers to the sport itself as GRID and describes it as "strategic team athletics racing".

[4] Because of its similarities to CrossFit, Budding was able to secure early investors, a television contract with the NBC Sports Group,[5] and an opening night in Madison Square Garden.

However, the NPGL halted operations midway through its inaugural season due to potential investors' backing out.

This led to cancellations of matches and caused the season to finish its finals in a format different from what was originally planned.

[10] The previously undefeated DC Brawlers lost their first ever match in the semifinal on September 2 to the Boston Iron.

[11] In the inaugural 2014 season, each Grid Match format was named after a prominent mountain, with current formats including Kilimanjaro, McKinley (later revamped slightly and called Denali in 2016), Pikes Peak, Everest, and Teton.

The athletic tasks performed incorporate weightlifting, gymnastics and bodyweight maneuvers denominated as "Elements" of each race.
