Phelps practiced a few of his famed trade mark strokes inside the pool at the Loyola College Fitness and Aquatic Center here. Weeks after he considered walking away from the sport for good, Phelps peppered a grueling training day with the wisecracks, playfulness and relentless teasing that his training mates had sorely missed as he wrangled with his future, reports the Washington Post.
After winning eight gold medals at last summer's Olympics in Beijing, Phelps took more than four months off and tried to determine if there was anything else for him to achieve in swimming.
Phelps said the answer suddenly became obvious and unarguable, but he can't pinpoint how or why.
"I literally just woke up on a Sunday and wanted to swim another four years," Phelps said.
"I don't know what it was . . . but it switched on in my head," he added.
