SAN ANTONIO -

On Sunday, Manuel Rodriguez, 67, took part in his 11th half-marathon since February.

It's a challenge he set up for himself to raise awareness about breast cancer in honor of his wife Lucy, who died on Feb. 10, 2010.

He did it despite his age, having a heart defibrillator and very little training.

"I thought about it and I think it's a matter of love," he said. "I wanted to do something extreme as a tribute to my wife but also for fundraising for research."

During his Marathon Crusades For Lucy, Rodriguez endured freezing weather, a serious thunderstorm and an injured calf and hamstring.

Sunday's Rock 'n' Roll Marathon in San Antonio was to be his 11th and final race.

However, his quest ended on a scary note.

Rodriguez said he was about 30 yards from the finish line when he was suddenly jolted.

"I felt this shock. It just knocked me to the ground," he said.         

His defibrillator had a misreading and jolted him unnecessarily.

Paramedics carried him across the finish line on a stretcher.

Rodriguez said he feels fine but is still shaken from the jolt.

He says it was worth it for Lucy and everyone else whose lives have been touched by breast cancer.

"If she were here, I know what she would do. She'd just stare at me and hold my hand and say, 'Thank you,'" he said.
