Gianna Lete is back from the Boston Marathon and wearing what she wore Monday. It's a sign of solidarity.
"To show that we're a strong group of people, both physically and emotionally, and that we're not easily broken," Lete said.
Lete's cellphone captured the race before the tragedy. Tens of thousands of runners had fans cheering them on.
"People are just ... it's just amazing to hear them cheer you on," she said.
Because of an earlier injury, Lete did not join her husband Eric until mile 19. They finished the marathon 20 minutes before the explosions and heard about it in their hotel.
"I just keep thinking about how lucky I am that the events turned out the way they did for my family and my friends," she said.
Three of Lete's friends, all from Ann Arbor, also were running in Boston.
"It was really hard to get texts and you couldn't call," she said.
It took an hour before she learned they were all safe.
"I keep thinking about the families that have lost people, lost that 8-year-old boy," she said.
Lete's 11-year-old daughter and 9-year-old son were staying in suburban Boston when the bombs exploded. She is trying to keep the explanations simple.
"I'll probably tell them there was some bombs and that some bad people did it on purpose," Lete said.
