The 300 yards each time must be completed in times of either 60 seconds or 70 seconds, depending on the team’s choice. The player is also given a rest time of around three minutes between each 300 yard run.
At the end of the test, the player has run the equivalent of nine football fields, or three fields broken down into 3 increments. If you think it sounds challenging, it can be. Given 60 seconds, that means you have ten seconds to run each 50 yard increment for each 300 yard phase.
While there are some players who don’t pass their conditioning test the first time, they are allowed to take it again. Even though some players loath the test, it’s not going anywhere anytime soon.
