Us At Our Best

The Boston Barstool Sports blog reports doctors and nurses who ran in the marathon ran back to volunteer to help the wounded after the bombing.

NBCSN reports marathoners ran to Massachusetts General Hospital to donate blood.

The Massachusetts Red Cross says so much blood was donated, no more will be needed.

Joe Andruzzi, a former player for the New England Patriots, was photographed carrying people out of the blast area. Andruzzi's brother was a FDNY firefighter on 9/11 and managed to escape the towers' collapse.

Local Bostonians opened up their homes to any marathoners displaced by today's events.

Carlos Arredondo, an anti-war protestor supporting a marathoner who was running for Arredondo's son who died in Iraq, was captured several times in photographs and on video. A Red Cross volunteer, Arredondo is seen in the above photograph pinching a femoral artery, and in the Steve Silva video helping clear debris off victims from the first explosion site less than a minute after the blast.
