You got to wonder after experiencing the attack at the Boston Marathon why Isaiah Douglas, who's from Savannah, Georgia, who ran in Boston would even consider running along with 20,000 people in Sunday's Rite Aide Cleveland Marathon.
35 minutes slower in Boston and Douglas might be dead.
Isaiah Douglas says "Yes I was shocked cause the left side where the bomb went off I was sprinting to the finish line."
