The Tunnel to Towers Foundation says its annual stair climb to the top of 1 World Trade Center is back on.

The second annual climb will take place Sunday, May 15.

Last year, 1,000 people raced up nearly 2,000 steps to honor the first responders who died on September 11, 2001.

The Durst Organization, which owns the building, originally said it would not host the event due to logistical concerns. Officials later said they would reconsider their decision after being pressured by the Port Authority, which owns the site, as well as Governor Cuomo.

This year's climb will go all the way up to the 102nd floor, eclipsing last year's finish line on the 90th floor.
