Endurance test, third degree


Today was supposed to be a special day with a special challenge. A 22 km hike? No, that’s not a challenge anymore. Carrying about 6 kg on your back? I want to get used to it, with tendency to carry even a bit more. Over a thousand meters of altitude? That’s more like it. Keeping the heart rate below 160? That could be really difficult, or is good preparation everything?
