Thousands of athletes will test their limits on Sunday, July 16, when they take part in the annual NYC Triathlon.

Competitors will swim the Hudson River before biking along Manhattan’s West Side Highway and running through Central Park.

But while those athletes compete in the grueling race, motorists will be competing for space on the roads due to some street closures.

The city's Department of Transportation released several street closures in the Bronx and Manhattan related to the race.

The following streets will be closed on Sunday from 4 a.m. to 2 p.m.:
