    Sarah McNair-Landry grew up in northern Canada. Her parents were Arctic guides, so it's not surprising that she wanted to explore from an e1. age. At the age of 18, she skied to the South Pole. She has been the youngest p2. ever to do this.

In 2007, McNair-Landry, her brother, and a friend decided to f3. snow-kite 2,300 kilometers across Greenland. She wanted to raise awareness of global warming, and s4. hoped to encourage a new generation of explorers.

In 2015, the 120-day trip was finished by her and a friend by dogsled. According to McNair-Landry, during that time, they o5. tried to make dogs happy because they didn't want to run all the time.
