I never actually fulfilled my dream of living in the mountains, but that's where I feel most at home. Whether it's the Himalayas, the Andes, Patagonia, or the Karkonosze range, the mountains are my place in this world. Running in the mountains is how I express my personality. It's a highly personal and moving experience every time. It's a way for me to meditate, a moment for me to think and to sort out in my head all the things I don't have the time and will to grapple with in my everyday life. I am not, and never will be, a frontrunner, but each event is a new challenge to me, one that pushes me to overcome my weaknesses as I train day after day. Running allows me to perfect myself both mentally and physically. My name is Mariusz Weber. I live in Berlin. I'm a trail runner.
