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.

As he neared the end of the race, an emotional Richard stopped at the Boston Marathon memorial on Boylston Street for several moments. He then turned and ran to the finish, pumping both fists in the air as he crossed the line.

He was quickly met by some of his family members, who greeted him with a warm embrace.

“So many people were out there for me,” Richard said after the race, per WCVB 5. “All my friends, my family. Motivation was the least of my worries. There was so many people there to support me. It was wonderful and I couldn’t believe it.” 

"This is Boston Strong. Everyone is." After finishing his first #BostonMarathon, Henry Richard said he hopes everyone continues to spread his brother Martin's message of peace https://t.co/bhRsoFz049 pic.twitter.com/aF1RmAJLmZ

Henry, who finished Monday’s race around 3 p.m., said the run was “years in the making.” He also said that he plans to enter the marathon again in the future.

“I’m just so glad I could finally be here,” he said, per NBC Boston. “So much emotion. I know Martin would have been doing it with me … I did it for both of us.”
