The field size for the 2015 race will not exceed 30,000 runners.
The next phase of registering for the 2015 Boston Marathon began Monday morning and runs through Wednesday evening.
There are 8,000 spots for qualifiers left in the race, and all runners who have met qualifying times can submit an application before the Wednesday deadline at 5 p.m. ET.
Registration for the race began last Monday and ran through Saturday night. Open slots remain, however, so registration was re-opened Monday morning at 10 a.m. ET for everyone who scored a qualifying time.
The process is not first-come, first-served. The Boston Athletic Association said if it receives more applications than there are open spots, “acceptance will be granted to the fastest qualifiers among the applicants.”
The total field size of next year’s race is 30,000 entrants, more than the 2013 number of 27,000. Following the terrorist bombing at the finish line of that year’s event, the BAA expanded the size of the 2014 race to 36,000.

The BAA said about 80 percent of the 2015 field will be comprised of runners who meet its strict qualifying standards, which amounts to 24,000 runners. The remaining 6,000 spots are allocated for charity runners and other special entries.
Runners in the 2014 race raised more than $38.4 million for local non-profits, according to the the BAA.
