A Bay Area runner preparing to return to the Boston Marathon a year after the deadly bombings said he is now running with a new purpose.
Ross-resident Dean Karnazes will run the marathon again to remember a family that he said will never heal from last year's tragedy.
"A young boy lost his life -- 8-year-old boy was waiting for his dad at the finish line," Karnazes said. "My son has waited for me at the finish line many times and tears well up in my eyes, but I think of that magical moment taken from them forever."
Karnazes also knows what he will do when he crosses the finish line.
"I'll get that medal around my neck and say a prayer for the family and vow never to take my family for granted," he said. "To appreciate and love them every single day."
