American Mikey Brannigan won the T20 men’s 1500m race today at the 2016 Paralympics in Rio di Janeiro. Brannigan clocked a 55.89 final lap to distance himself from Poland’s Daniel Pek (silver in 3:56.17) and Iran’s Peyman Nasir Bazanjani (bronze in 3:56.24) to take the gold in 3:51.73.

The T20 classification is for athletes with an intellectual disability. Brannigan, who has autism, ran a 3:57.58 full mile at the Sir Walter Miler, held earlier this year in North Carolina. After a standout high school running career—which included a 4:03 mile in 2015—he started training as a member of Team USA as a Paralympic athlete. He has set numerous Paralympic records over the past several years.
