BROOKLYN - The third annual Brooklyn Marathon was held in Prospect Park this morning, but organizers are hoping they can take the race to the streets in the future.

This year's race featured 500 runners, which is twice as much from the inaugural marathon. But race organizers say that because the race is run in the park, there's a limit to the amount of runners the park can support.

Race organizers are petitioning the city to move the race to a new route that starts on the Brooklyn Bridge and ends on Coney Island. They say they're hoping to attract 25,000 runners to the 2015 race.
