2008_12_marathon.jpgDespite rising numbers of local participants running in its races, the New York Road Runners announced that will put caps on how many entrants they allow starting next year. The races in Central Park will now have a ceiling of 5,000 runners--a number surpassed by over a third of 27 its races this past year. The change is being made to enhance the overall experience of runners, not for any specific health or safety concerns. The 5,000 cap will not apply to the two biggest races--the New York City Marathon and NYC Half-Marathon, much bigger affairs--but those will now see limits as well. Mary Wittenberg, NYRR President, told the Times, “The biggest change is that it will force runners to decide early what races they want to run in. Up until now, they had the luxury of waiting basically until race day."
