Cara Bass still remembers “those two sounds.”

She crossed the finish line of the Boston Marathon forty-five minutes before the April 15 bombings and was standing two blocks from the site of the blast.

“Hearing it and the panic, the bomb squad gear, the fear,” she recalls.

Four months later, Cara has transformed that fear into fuel. She just completed the Leadville 100 in Colorado- a grueling race through the Rockies where she climbed 16,000 feet to finish the race in 29 hours, 48 minutes.

She proudly wore her Boston Marathon jacket and shirt in Colorado and ran into strangers who were wearing the same.

“Its funny how I felt more compelled to walk up to them because they were there,” Cara said. “It was kind of like a camaraderie of Boston survivors."

But she says she and her fellow runners don't talk about the bombings. Instead, what they witnessed in Boston has propelled them further, pushed them harder.

"Every day is a new day. Every day we go forward and start a run wanting to get better at what we do,” she says. “And I don’t think the bombing is ever going to take that away from us.”

Cara plans to run a 50 mile race this fall and her second 100 mile race next year. And with each mile, she puts the terror she felt in April far behind her.

"Somebody tried to instill that in us. And we said ‘no, it’s not going to happen,” she said.
