ALPINE TOWNSHIP, Mich. (WOOD) — Only a few weeks after setting a new collegiate record for the 800-meter run, Kenowa Hills graduate Donavan Brazier will compete to represent the U.S. at the Rio Olympics.

The 19-year-old Texas A&M freshman ran the 800 in 1:43:55 at the outdoor national championships in Eugene, Oregon earlier this month, winning the national title. The time was two seconds better than his previous personal best and the second fastest in the world for the year.

“I have no clue” where that record-breaking time came from, Brazier told 24 Hour News 8 Monday. “I wish I could tell you. I have no clue where that came from.”

“It just completely blew me away. I was just going for the win for that race,” he continued. “When I saw the time and I just looked up, I was like, ‘Thank God. Thank God it’s over. Thank God I ran a good time.’ I was just happy.”

1:43 isn’t just a “good time.” It’s world class. It’s the kind of time that taxes your body and tests your toughness.

“No matter what you do, it’s going to hurt,” Brazier said. “It’s going to hurt if you don’t run as fast, and it’s going to hurt if you run fast. If you don’t run as fast, after the race it’s going to hurt. And if you run fast, during the race it’s going to hurt,  but you’re going to feel good after the race. So you’ve just got to give yourself that mindset: It’s going to hurt, it’s going to be pain, you just have to go through it.”

Immediately Brazier broke the collegiate record, speculation arose of a trip to Rio. And Monday, Nike announced it was signing Brazier to his first professional contract.

“I just wanted to kind of make my name a little bit known my freshman year,” Brazier said. “I didn’t expect it to be this big, let alone win a national championship, so I’m very, very, very pleased with my freshman year and my decision to turn professional.”

The Olympic games, he said, have always been a dream — but he never thought he’d be giving it a shot so soon.

“That’s always the goal for every track athlete, I think, is trying to make the Olympic team, which is pretty much the hardest team to make in the world,” Brazier said. “I didn’t even realize until two weeks ago that I was actually going to do the Olympic trials. I was planning on doing the World Junior meet out in California, but after I made my decision to go pro, I knew that trials was the next step for me.”

Monday, Brazier worked out alone at Kenowa Hills High School.

“If there’s people watching me, I always have that little extra motivation to run fast and not look stupid while I’m running,” he said.

He’ll have plenty of people watching soon enough. Tuesday, he left for the Olympic track and field trials in Eugene. Qualifiers for the 800 are Friday, semifinals are Saturday and finals Monday.

The question will not be just whether Brazier can make Team USA, but also whether he can beat that 1:43.

“I thought that 1:47 my senior year (of high school) was what was left out of me, but apparently I had a 1:43 in me, so I think it’s just limitless,” he said.
