North County mom on quest to complete marathon ‘Grand Slam’

ENCINITAS, Calif. -- Software engineer Vivian Lee and mother of two recently completed the world's toughest foot race, The Marathon Des Sables, in Morocco.

She is now on a quest to run marathons on all seven continents and the North Pole, in just under eighteen months, making her the first Chinese American woman to do so.
