As we know, many of those injured on Monday at the Boston Marathon lost a limb.
Traum lost a leg in a automobile accident when he was 24.
It was only then that he began running.
Traum finished the marathon in Boston this past Monday.
He ran with 35 fellow amputees all members of Achilles International, the organization he founded that supports disabled runners from around the world.
Anchor Aaron Schachter spoke with Traum about his story.
