In a conversation at the end of Sunday’s walk, we realized just how much energy is actually involved in such a trek. Our vertical ascent was about 1100m, spread between climbing Yoke and following the ridge of the Kentmere Horseshoe. That is about 75kg of me personally, plus a pack. Imagine me falling from 1100m up, and you begin to appreciate the gravitational potential energy built up through the (not entirely efficient) expenditure of chemical energy. We also traveled more than 20km, as the crow flies. Then, there is the fact that we had to absorb all the energy from all the descents into our muscles and dissipate it. Add in the energy required to keep us warm, balanced, and thinking, and you are racking up a good number of calories.
It’s amazing how far some dry cereal, two sandwiches, a couple of chocolate bars, and ones various short and long-term energy stores can go. The fact that I didn’t feel unusually hungry at any point during the weekend suggests that those stores were not seriously depleted.
As you may guess, this weekend included a lot of interesting discussion about physics, biochemistry, and physiology. We also learned a good bit about sheep.
