The story
The Marathon des Sables is often called the world’s toughest footrace: six stages of roughly 250 km (some years over 300 km) across the Southern Moroccan Sahara, self-sufficient — you carry your food, your tent, and most of your gear, from dune to dune.
Achim’s journey began far from the desert: with a first 10 k, then a first marathon, and a slow, deliberate build-up of distance and — just as important — of the right material, learned the hard way and then the smart way.
