The New York City Marathon will set another new record Sunday when 47,000 runners participate in the iconic five-borough race.
The marathon has grown almost exponentially since its inception in 1970 when 127 runners toed the starting line.
And according to a report in the New York Daily News, organizers foresee a day when the race evolves into a two-day event with 100,000 runners participating.
Race director Mary Wittenberg told the paper that demand keeps increasing and that creating two separate races on Saturday and Sunday could be key as the event edges closer to the 100k mark.
Such a plan would need city approval and would likely face opposition. The current one-day race already wreaks havoc with New York City traffic patterns.
