Boston Marathon Survivor Says She Ran 2016 Race to Say 'Giant Thank You'

Adrianne Haslet-Davis returned to the race where she lost her leg.

— -- Three years ago, when terrorist bombs rained down on the Boston Marathon, Adrianne Haslet-Davis and her husband were injured while on the sidelines.

Haslet-Davis had to have her lower left leg amputated. She had been a professional ballroom dancer at the time of the 2013 blast.

Monday, she returned to the 26.2 mile race -- this time as a competitor.

"I wanted to say a giant thank you to anyone who's ever reached out, given a hug or a letter or kind words to myself and all the other survivors," she told ABC affiliate WCVB-TV in Boston.

"Two years ago I was lucky enough to meet Adrianne Haslet, a survivor of the 2013 Marathon bombings," he wrote Monday on Facebook. "She's on the course now, running the race for the first time -- with a prosthetic leg. Adrianne thank you for being my inspiration!! #?BostonStrong?."

Haslet-Davis is slated to cross the finish line Monday evening and expects it will be an emotional experience.

"I just hope I have enough hydration to cry and run at the same time," she said.
