Ever had to turn around on a hike or an adventure because you were completely out of breath? Alphonso Duncan, a Boost Oxygen user, can empathize with that feeling. In the video below, Duncan chronicles his journey to the trailhead and up Mount Baldy via Devil’s Backbone in California. The trail clocks in at 12.9 miles with an elevation gain of 3,602 feet.

In this video, Duncan describes himself feeling lightheaded at the top, but after using Boost, he says he felt “brand new” and “ready to go again.” Another hiker even took one of Duncan’s cans of Boost off his hands. Check out Duncan’s experience below, and remember, we always welcome feedback.
