San Antonio runners are beginning to return home from the Boston Marathon with tales of tragedy and triumph.
Robyn Cardy had just finished the marathon Tuesday when the explosions happened.
"As I was walking to the bus, I heard the explosions and immediately felt that something bad had happened," Cardy said.
By Tuesday, Cardy was back home, limping a bit from turning her ankle at the marathon, and glad to be alive.
She said if she had finished five minutes later she and her two kids would have been at the scene of the explosion.
"It really didn't even hit me until we got on the bus and my son had shown me a picture of the actual site of what had happened and I just broke down crying," Cardy said.
Larry Macon has run in more than a thousand marathons and, as an older runner, he was a bit behind Cardy when she finished the race.
"We're running and we're at mile 23, all of the sudden police cars, the sirens go whizzing by us,” Macon said. “I wondered what's going on."
When Macon got a mile from the finish line, the race was stopped.
"There are people that this is their only time they'll ever get to Boston and they're crying, they're frustrated, they're tired," Macon said.
Even with the tragedy, he sees the bright side.
"I'm very glad that there were only three people killed and 150 wounded because there were tens of thousands (of people there)," Macon said.
And both Macon and Cardy wonder who would do such a thing.
"I don't understand why somebody can be so angry to want to hurt so many innocent people," Cardy said. “There was just complete chaos in the entire city, it was a mess, it was horrible. Ambulance, police, people were just scattering."
Macon told a harrowing story of being told he could not return to his hotel.
He decided to find a driver and head to the airport.
“I got to the airport wearing my shorts and having my driver’s license and nothing else,” Macon said.
He was without a credit card but said the generous people of Boston took care of the runners.
“People from Boston took runners in, they took them to dinner,” Macon said. “They said, 'Did you run in the Boston (Marathon) today?' I said, 'Yeah.' He said, 'Come on in, everything's on the house.' I get on the airplane, I can't stop the flight attendant from bringing me drinks."
Cardy said despite the tragedy, she will go back to Boston for the marathon and that no matter who these terrorists are, they will not take away an American tradition.
