Dear Keenan, this is the hardest letter that I've ever written and I'm certain it will be the hardest letter that you've ever read

For if you are reading my words then I must be gone

Something unpredictable and horribly unimaginable has happened to me in Antarctica.

At this moment I wish my arms could reach out from these pages and wrap around you to

comfort you like no other.

I would take your hand in mine, whisper in your ear tell you I love you and everything will be okay.

Of all the things that I've ever done my life, nothing compares to being your mom.

Nothing. How could I choose Antarctica over spending the rest of my life loving you

and watching you grow into a man. I promised to be safe. I promised I would

be back. Part of living, really living, is to continuously grow and learn and challenge your limits.

I believe to my core that the best way to live a good life, a full life, a happy life is to seek

challenge and to take risks, try new things, and push into the unknown. It takes a certain kind of person, a bold one, a strong one, a wild one, to pursue an adventure like the one taken on by today's guest.

In 2014, Chris Fagan and her husband Marty left their 12 year old son at their home in Washington

State and they flew to Antarctica. There they spent 48 days

skiing to reach the South Pole setting a world record.

I'm Shelby Stanger and this is wild ideas worth living.

Chris Fagan calls herself ordinary like anyone else, but she spent decades pursuing wild ideas.

She met her husband while climbing Denali in Alaska unguided.

She founded an innovation consulting company. She's run several

ultramarathons. But the idea for her wildest adventure, it came with a realization

that she and her husband's bodies, they were aging.

The planet was warming.
