Heather Abbott was at the finish line of the Boston Marathon on April 15, 2013, when two bombs went off. One of her feet was severely injured in the blast and was eventually amputated.
Nearly a year later, the 39-year-old human resources specialist from Newport, R.I., was back at the same site, this time with a group of fellow survivors of the bombings who crossed the same finish line Sunday to complete the final stage of a cross-country relay that started four weeks earlier in Santa Monica.
Later in the day, a program honoring the victims at Hynes Convention Center is expected to be attended by Vice President Joe Biden, among others. Several survivors are scheduled to speak.
But perhaps the biggest tribute of all will take place several days from now, when thousands will gather on Monday to take part in the 2014 Boston Marathon.
President Obama, who is observing the anniversary with a private moment of silence at the White House, said in a statement that this year's race will “show the world the meaning of Boston Strong as a city chooses to run again.”
