Really determined

Amy Palmiero-Winters certainly is. She just spent six days running in the Sahara desert. She competed in the Marathon des Sables, which means she ran over sand dunes, rocks, dry valleys, stony plateaus and salt flats in southern Morocco. And she had to carry a backpack containing everything needed for a week in the desert: food, sleeping bag, compass, headlamp, venom pump to minimize any bites from snakes and scorpions.

She is a single mother with two teenage children. She uses a prosthetic leg as Her lower left leg was amputated below the knee in 1997 after a motorcycle accident. Here she is in training.
