My Journey to Recovery

At the end of every day, I would take my favorite drink, tequila straight up in a large shotglass. There was no need to put anything else with it. I would pull it out of the freezer with ice crystals still glistening on the sides of the bottle as soon as I got home. I would think about this drink all day. I gently poured the booze in a shot glass as I tried to savor this moment but without hesitation, tossed it in my mouth. I couldn’t wait for this.

5 Ways to Build a Resilient Backcountry Body

I am frequently asked about the best way to train for a thru-hike. While training is important, there is no protocol that will prepare you to hike 8+ hours a day, day after day. However, what you can do is prepare your body to handle that volume of effort. In essence you’re building a resilient body that is well-equipped to adapt to the rigorous demands of a long-distance hike. Even if a thru-hike is not in your future, these strategies promote overall health and ability to adapt to the stressors of everyday life as well.
