Emotions will be high on Sunday when the New York City Marathon steps off for the first time in two years.
The run was canceled last year because of Sandy.
And then, six months later, the deadly bombing took place at the Boston marathon.
Organizers on Wednesday painted the finish line in Central Park.
This year, a yellow line was added as a way of paying tribute to victims and first responders in Boston.
"When it came time to planning this year's race we really wanted to remember those in Boston, and what better way than as the runners are hitting this final stretch to, the last steps of their life goal is to crossing this finish line to look down and see the yellow line of Boston, and remember and honor Boston, and be inspired to finish this race," said New York Road Runners President CEO Mary Wittenberg.
The marathon snakes it way from Staten Island, through Brooklyn, Queens, Manhattan and the Bronx, before runners return to Manhattan to cross the finish line in Central Park.
Organizers say everything has been done to ensure the safety of runners and spectators this weekend.
