Boston Marathon registration for qualifiers closed at 5 p.m. on Wednesday, according to the Boston Athletic Association.

With an expected field of 30,000, registration will not reopen on Monday, September 22 since more runners with qualifying times have signed up than there are spots available. According to Runner's World, next year's marathon will feature 24,000 qualifiers.

Due to the number of applications, the B.A.A. notes that additional time is needed to process all registration requests and confirm claims of qualification. All registrants will be informed of their acceptance or rejection by Wednesday, September 24.

The estimate field size and the quickness with which registration slots filled up means the 119th Boston Marathon will be one of the biggest races in the event's history. Last year, the 118th marathon boasted an unprecedented 36,000 entrants. Many were runners who, due to the previous year's bombings, were unable to finish the race. The B.A.A. granted them the chance to finish.

If you weren't able to register, don't fret. The B.A.A. has released details concerning the 120th Boston Marathon on April 18, 2016. The qualifying window began on Saturday, September 13, and registrant age group is determined by age on race day.

The 119th Boston Marathon is scheduled for Monday, April 20, 2015.
