It was an iconic moment from the Boston Marathon bombings, an elderly runner buckling to the ground as the first bomb detonates.
The photo of 78-year-old Bill Iffrig sprawled out on the street was on the cover of Sports Illustrated.
He actually got up and finished the race and now he's back at it, running in his first race since Boston, a half marathon in Spokane, Washington.
He wore the same orange singlet that he wore on that fateful day three weeks ago.
He said, "I didn't fall down once!"
Another hero of the Boston Marathon, Jeff Bauman, whose horrific injuries were captured in a heartbreaking photo, made a surprise appearance at the Boston Bruins playoff game. The crowd went wild when Bauman, who lost both legs in the terrorist attack, appeared on the ice.
Meanwhile, lost video shot by a Boston Marathon runner has just been recovered.
Katie Eastman is a reporter for the Boston Herald. She was running the marathon holding a video camera when the bombs went off at the finish line.
"As you can see in the video, we didn't know exactly what was happening, we just kept running," she told INSIDE EDITION.
Like thousands of other confused and frightened runners, she was desperate to reach her family, who were waiting for her at the finish line. A Good Samaritan let Eastman use a cell phone to reach her sister. Katie's family was safe.
At mile 25, police stopped her from finishing the marathon.
In the video police say, "Guys, it's done, the marathon's over!"
"What makes the video so powerful for me and a lot of other people watching is to see how happy me and so many people were before it turned to tragedy," said Eastman.
