“People have to get out to nature! It’s calming, nature gives us life basically. I think it’s essential to our psyche to get out,” Marshall says. It’s the topic of his latest book “Both Feet on the Ground,” which came out in Spring 2019.
He addresses how food, nutrition & common-sense play a big role in his athletic accomplishments and how his connection to agriculture and nature is the glue that ties it all together.

With everyone sheltering at home, this is a great time to read Both Feet on the Ground. In addition to reading about some of Marshall’s exciting adventures in the mountains, deserts, and beyond, Both Feet encourages you to get outside, know where your food comes from, disconnect from gadgets, face fears, value what’s important, tame the mind, and dream of your next adventure; all things that are especially vital today.
