One of my main goals for fitness is to be able to undertake something like this hike. While it was a physical challenge, I had cardiovascular fitness, endurance and strenght from my cyclilng. None of it was as specific as months spent on hiking trails, but enough to match my 15 year old son’s endurance at least. By the way, that’s him at the top of the ravine, posing very nicely for the image.
Here’s the Google Earth projection of the GPS track up the mountain.
