Two athletes trekked 75 miles from Long Island to Lower Manhattan to honor the victims of the September 11th attacks.

Runner Eva Casale and hand-cyclist Michael Roesch called their journey "Footsteps for 15" in honor of the upcoming 15th anniversary of 9/11.

They began their 18-hour trip in Manhasset and stopped to place wreaths along the way.

It all ended at the National September 11th Memorial & Museum.

"We stopped at a lot of memorials in Queens, Brooklyn, Staten Island, and here in Manhattan, and I think just seeing all those that were lost and keeping them in our hearts and what we would do on the mission — I think that was keeping me going, knowing that we unfortunately lost them, and the least I can do is honor them on this day," Casale said.

The event raised money for the group Tuesday's Children, which helps families of 9/11 victims, first responders, and military families.
