Registration starts today for the 2014 Boston Marathon.
The Boston Athletic Association will be accepting 9,000 more runners this time.
They're making room for the more than 5,000 runners who didn't cross the finish line after two bombs exploded.
Three people were killed, and hundreds were injured.
They've also invited runners who want to honor victims of the bombing.
The race is set for April 21, 2014.
