Runners in the 2014 Boston Marathon raised a record $38.4 million for charity, nearly double the $20 million raised in 2013, the Boston Globe reports.

More than 300 organizations received funds raised by many of the 32,408 people who ran in this year's expanded field, which included about 5,600 who were unable to finish in 2013 when the race ended with the terrorist bombings that killed three people and wounded more than 260 others. For this year's race, 3,150 slots — up from 2,600 last year — were reserved for those running for charity, including local hospitals; One Fund Boston, which raised $816,000; and the Martin W. Richard Charitable Foundation — named for the 8-year-old Dorchester boy who was killed in the attacks — which raised $1.25 million. In addition, runners raised $120,000 for the Krystle Campbell Scholarship Fund at the University of Massachusetts Boston and $207,000 in memory of Massachusetts Institute of Technology police officer Sean A. Collier, who was killed in a confrontation with the Tsarnaev brothers, the alleged bombers.

"This year's Boston Marathon was like no other that we have witnessed," said Tom Grilk, executive director of the Boston Athletic Association, which organizes the race. "We worked in cooperation with the community, especially the eight cities and towns which comprise the Boston Marathon route and the Commonwealth of Massachusetts, to accommodate as many participants as possible, and we were delighted that so many chose to channel their dedication and commitment towards fundraising for worthwhile causes."

Meanwhile, One Fund Boston has finalized its protocol (2 pages, PDF) for the distribution of more than $19 million in donations received after it distributed $61 million last year to the bombing victims and their families. Amputees will be given top priority, followed by the families of those who were killed, then those who suffered injuries such as lacerations, burns, hearing injuries, ringing in the ears, abrasions, nerve damage, puncture wounds, post-concussive syndrome, and traumatic brain injuries. One Fund Boston also will work with area hospitals to create a medical collaborative that will provide evaluation, treatment, care coordination, and support for survivors with invisible wounds, including tinnitus, hearing loss, mental health and post-traumatic stress, and traumatic brain injury. Fourteen survivors who say they suffered traumatic brain injuries had questioned the fund's compensation formula, which resulted in their receiving only $8,000 in the initial distribution.

"We have taken invisible injuries very seriously," Dot Joyce, a spokesperson for One Fund Boston told the Globe. "Not only are we offering cash gifts to those individuals, we are also investing in longer-term programs and services that will significantly help with those specific injuries. There will never be enough money to compensate everyone for all that was lost."
