Illustration inspired in the Alex Megos quote: "Carrots for power".
The german climber developed some years ago this idea:
"I was looking for a vegetable that I could take to the crag, one that wouldn’t get mushed in your backpack and that was healthy. Most other vegetables, besides carrots, are either not as common, or aren’t very delicious raw. Carrots are the perfect vegetable to eat at the crag because you can eat them raw, bring them everywhere, and they last for a long time."
