BALDWIN: Two words for you this afternoon, Boston strong. If anyone dares to doubt the strength of that city and its people, just watch the Boston marathon today. It has been three years ago since the terror attacks killed three people and injured hundreds right along Boylston Street there. One of them, Adrianne Haslet- Davis. She is a dancer who lost her leg in the bombing. Adrianne was never a runner. But right now, I can tell you she's on that course at the Boston marathon using her prosthetic leg. And I talked to her recently to her training and she told me the running wasn't the hardest part.</s>ADRIANNE HASLET-DAVIS, BOMBING SURVIVOR: The mental challenge is the most difficult. You know, mentally for me personally, putting on my leg every day, waking up in the middle of the night to walk to the bathroom and then getting angry that I have to put on the leg and then staying up all night angry. It's a daily challenge. And that mental game played with that is really tough.</s>BALDWIN: Not only did you FOX trot across the finish line with your prosthetic leg, you crossed the finish line with your brothers in 2014, you will be running the 26.2 mile course in just a couple of weeks. And from what I read, you said once upon a time you didn't even like running. So my hat is off to you, sister.</s>HASLET-DAVIS: Thanks so much. Thank you. You know, it's the least that any of us could do as survivors to say a giant thank you for everyone who has ever reached out or said or relishes or wraps their around someone on the street. And it's a giant thank you to Boston.</s>BALDWIN: She's been updating us. If you are following our twitter, she had issues with her prosthetic but she did say Patriot's quarterback Tom Brady cheering her on. He posted on Facebook today, thank you for being my inspiration. Thank you, Adrianne Haslet-Davis. And thank you for being with me. See you back n "</s>NEW DAY" 6: 00 a.m. Jim Sciutto is up next with "THE LEAD."
