In 2013, Rebekah Gregory cheered on her then-husband's mom near the finish line of the Boston Marathon.
Her cheers turned to screams after two bombs detonated near the marathon's finish, leaving Rebekah fighting for her life.
Following at least 35 leg surgeries, including the amputation of her left leg, Rebekah Gregory returned to Boston this spring -- not as a spectator, but as a race participant.
Speaking to espnW, Gregory shared her experiences from that day two years ago, as well as the details of her long recovery and triumphant return to this year's Boston Marathon.
After attending the 2014 marathon in a wheelchair, Gregory was convinced she would be able to fully run the 2015 event with the help of a prosthetic leg.
She was crushed when doctors told her she couldn't run the full 26.2 miles, but she refused to be defeated.
Despite losing a leg, going through the painful recovery process, traveling to Boston for the trial of Dzhokhar Tsarnaev and having her dream of fully competing in the marathon delayed, Rebekah Gregory continues to fight.
