Oldest woman marathoner

San Diego

A 92-year-old US grandmother has become the oldest woman to finish a marathon, when she crossed the finish line of a San Diego 26-miler on Sunday, race organizers said.

A smiling Harriette Thompson, aged 92 years and 65 days, was cheered by dozens of onlookers and supporters as she completed the Southern California event in seven hours, 24 minutes and 36 seconds.

Speaking to her hometown newspaper, the Charlotte Observer, Thompson said she felt "a little stiff" after the race.

"I was really tired at one point. Around mile 21, I was going up a hill and it was like a mountain," she said.
