Boston Marathon bombing survivor crosses line, finishes race
Gregory ran the final 3.2 miles of the course.
"Just to know that I was crossing the finish line on my own foot and I wasn't in a wheelchair like last year and I wasn't laying on the pavement fighting for my life like the year before," Gregory told ABC News after crossing the finish line. "I've come a long way and I'm just going to keep going because there's no stopping me."
The Boston Marathon bombing in 2013 had killed at least 3 people.
