Henry Richard, whose younger brother died in the 2013 Boston Marathon bombing, completed the race for the first time on Monday, finishing an emotional 26.2 miles with an embrace from his family.
Henry was 10 years old when his brother, eight-year-old Martin Richard, was killed. Martin would have turned 18 this June.
Their sister, Jane, lost her left leg in the attack.
Henry, now 20, was among the more than 28,000 runners in Monday’s marathon. During the race, he wore a yellow Team MR8 jersey and had his siblings’ names written on his arms in marker.
