Donavan Brazier broke Jim Ryun's NCAA record for the 800 meters on the 50th anniversary of its running as the Texas A&M freshman ran 1:43.55 to win his first NCAA outdoor title.

Brazier is now the seventh fastest American of all-time at the distance.

The following were Brazier's 200-meter splits throughout the race, according to Kevin Liao of Sporting News: 24.13, 26.36, 25.98, 27.10

Brazier may elect to compete at next month's U.S. Olympic Trials, which will determine the team that will compete at the Summer Games in Rio de Janeiro. After the race, he said  he has not made a decision on whether or not to compete at that level or focus on the World Junior Championships.
