4. Czech Republic, Germany

I turn down the offer of a room at the CP1 in Krupka. I’m determined to push on, and after quite a bit of faffing, I’m back on the road. The roads in Bohemian Switzerland National Park are beautiful but a bit choppy for this tired soul, and the lack of sleep over the past few days has left me feeling depleted of energy in the hot afternoon sun.

Soon after setting out I see a tree by a river offering up some cool shade. It looks idyllic and I decide to have a power nap to replenish my batteries. I lie down on the grass underneath the tree and immediately fall asleep. I’m not sure how many hours go by, but when I awake the sun has moved across in the sky and I'm lying in direct sunlight. Feeling groggy, I gather everything up and get back on the saddle.
