"It was awesome, an absolutely surreal experience," former New England Patriots fullback James Develin said after finishing his first marathon. Develin, 33, completed the Boston Marathon on Monday in 4:27:17. "It was really special. I'm really glad that I was able to do it and to raise money for the Joe Andruzzi Foundation," Develin told reporters after crossing the finish line.The foundation helps New England cancer patients and their families by contributing financial support for everyday expenses like rent or utilities. Develin compared the experience of running a marathon to his years in the NFL."You're willing to put your body through the wringer and just, you know, embrace the pain a little bit. That's kind of what I did for the last four and a half hours. No step was comfortable. Every minute that ticked by, I was getting more and more depleted, but it feels great crossing that finish line," he said.
