Mary Vancore (right, green shirt), from Tallahassee, Fla., is representing her running club in her second marathon. "I'll be OK because I train in Florida," she said. Dan Tirozzi (white t-shirt) from Los Angeles is running his 13th marathon while Kevin Abbott (center), from Boston is running his first marathon today. "I'm 25-years-old so I should be fine," Abbott said about any concerns with the heat.
