"I've always been a big fan of the outdoors, ever since I was very young. I’m from Þingeyri in the Icelandic Westfjords and when I was growing up there were no cinemas or anything like that. I was just constantly skiing, skating, or running around in the mountains and that's how it's been ever since."

Guðrún Sveina Jónsdóttir will turn 79 years old this summer but says she doesn't feel old at all. She worked all her life as a midwife in Iceland’s biggest hospital, Landspítalinn, and often jokes about how she simply doesn’t know how to do anything else. "I was always on the go there too, you can't really sit a lot while doing that job."

Guðrún is usually out and about at 7 am every morning, alone. "Other people only slow me down." She has walked all the main hiking trails in Iceland - and when she is not walking, she goes to the gym or plays golf. Guðrún has hiked all over the world, for example, the Way of St. James where she went with her daughter and granddaughter, and hiked a total of 319 km in fourteen days. She lives on the sixth floor and never uses the elevator.
