Amby Burfoot, the winner of the 1968 Boston Marathon, remembers what it felt like to cross the finish line. He was elated, and more than anything else, fatigued.

"I remember collapsing like a piece of cooked spaghetti," Burfoot told Boston Public Radio during an interview Monday.

Since then, Burfoot has become a running legend and a staple of the Boston Marathon, having run the last six years in a row.

This year, Burfoot decided to give himself some well deserved rest, but the excitement of the marathon still gets to him.

"Just being here, you just feel the energy and you think, I want to be out in Hopkinton and do it again," he said. "It is just a particular thrill to come back to Boston every year."

Burfoot's new book is, "Run Forever: Your Complete Guide to Healthy Lifetime Running." He joined BPR to talk about all things Boston Marathon.
