BOSTON (AP) — The Boston Marathon is full.
The Boston Athletic Association said Thursday that registration for the 2013 race has closed. More than 20,000 runners who met a new, more difficult qualifying standard, signed up since registration opened on Oct. 11.
Other runners still have a chance to participate as part of a charity program that has raised more than $150 million in the past 25 years.
The marathon was forced to change its registration process two years ago after a rush of applicants filled the field in eight hours. That broke the previous record of 65 days.
The 117th Boston Marathon will be Monday, April 15.
