You probably wouldn’t think so, but being a backpacker is a numbers game. We constantly have numbers in our head. Mathematics in action. Always adding, subtracting, calculating and estimating.
Running through our heads is our pack weight. Or, the time we pushed off from the trailhead. It’s what the elevation is and what gain (or loss) we’ll see. Or, how many miles to the next water source? To the next camp site? It’s how many miles it is until the next big ascent.
No numbers are as important, though, as those it takes to know where we are. With the invaluable help of apps like Half-Mile and Guthook, we know where we are within a few feet of the trail. We’re not sure how the pioneers found their way across the Rockies without GPS. We’re just glad that we have the help with all the math.
