Last year on April 15, the city of Boston was struck by tragedy - terrorist attack on the city's most famous race. Three people lost their lives and more than 260 runners and spectators were injured at the Boston marathon.
David Mallams of Rapid City ran in the race last year. He finished about a hour and 25 minutes before the bombs went off.
"I was about a block and a half away when I heard the first explosion. And then I heard the second one, I thought they were like celebratory cannons," said Mallams.
He didn't realize it was a bomb until an hour later.
Mallams said he watched the scene unfold on television, grateful he finished when he had.
"I was just thankful that it didn't go off when I was going through. It was my youngest daughter's birthday that day," said Mallams. "I just thought that would be a really bad thing for her to remember."
Mallams said that the running community and nation will persevere.
"I think the numbers of runners are up since the bombing to think it's going to weaken the running community, I think it's a mistake to think that," said Mallams.
The 2014 Boston Marathon race will be Monday, April 21.
