Buzz and Corrine chat about Buzz's skyrace experience in Norway. Then Corrine interviews Zoë Rom and Tina Muir about their new book, Becoming a Sustainable Runner: A Guide to Running for Life, Community, and Planet.

"A healthy planet depends on your thriving and your community's thriving. Your running depends on a healthy planet and a healthy community. A healthy community depends on healthy individuals and a healthy planet to exist," said Zoë.

And Buzz answers questions from Scott on pickle juice and mustard and talks to race director Samuel Hartman about why ultrarunning is not in the Olympics.
