ADAC The limit is only me book

An adventure as big as the whole world
Once around the world, in the triathlon disciplines of swimming, running and cycling. Left to his own devices, Jonas Deichmann has achieved the impossible: while the world remains in lockdown, he circumnavigates it in 14 months full of borderline experiences and moments of great happiness. Deichmann swims across the Adriatic Sea, rides his bike 20,000 kilometers to Vladivostok and runs through Mexico in 120 marathons. Accompanied by people, young and old, who join him to become a small part of his adventure.
The end result is an incredible story of courage and motivation, of moving mountains, of the magical power of candy bars and the boundlessness of our world.
