The heat in Extremadura. Sunflowers in Trujillo. The endless baking plains in "the devil's frying pan " where everything is dry and yellow and the grains of sand are red hot.
Being run into in Barcelona. Luckily the speed wasn't so great, so it didn't result in anything more than road rash on the knees. I had just gotten up on the bike when I heard him shout behind me. But too late. The moped hit me from behind with a crash. In one second I had both a thousand and no thoughts, and then I was lying on the asphalt.
The uphill climbs going up to Cebreiro. A three hour climb with heavy panniers up to 1337 m above sea level. My thigh muscles didn't want any more. No matter how much I wanted them to, my legs just wouldn't go around.
The rainy weather in Germany. One day is fine, but not 3-4 in a row.
Headwinds in Southern France. A strong breeze right in your face. Every meter was a struggle.
Waking up in the morning with your tongue stuck fast to the roof of your mouth. I ran out of liquid the day before and all the shops and gas stations were closed.
That it was always siesta when we were hungry and ready to take a break.
