Jo Dee Messina completed her first Boston Marathon on Monday (April 17) with a time of 5 hours, 47 minutes. She finished the race an hour later than she expected after injuring her left knee about halfway through the course. "I don't know what happened," she wrote in her online journal. "I don't know how I did it, but I spent a good deal of time in the first aid tents trying to get them to patch me up enough to get to the next first aid tent -- and so on and so on. I'm going to do more marathons, though. I'm determined to get that 4:40 time."
