In March 2022, I started running 2500 km through Scotland, England and Poland. The challenge begins at John O'Groats, across the northern Highland coast to Durness. Then I turned towards The Isle of Sky island, which I circled around and continued down the country to England and Wales. Running through the Highland was one of the most challenging experiences I've ever had. I spent two months running over dozens of hills and mountains in unexpectedly changing weather conditions, from snow, rain, and strong winds to clear skies and beautiful sunshine, all in a matter of hours. In addition, long distances, sometimes up to 80 km, without access to water and food. I completed the United Kingdom part in Chester and continued running through my homeland, Poland.
