I would like to send my achievement. I ran around Poland in the self-supported formula. Official borders of Poland according to wikipedia have 3511 kilometers. I am the first one who so thoroughly circled Poland along the borders, adding several hundred kilometers. Many areas were overgrown or marshes or farms were built on the road. So I have to change sometimes track and I ran around farms etc.
I was running with a backpack weighing about 7 kilograms in which there were things for disguise, electronics and extra shoes. I ran along border with Germany, Czech Republic, Slovakia, Ukraine, Belarus, Lithuania and Russia.
I got six tripoints, places on the border where three countries connect, e.g. Poland, Germany, the Czech Republic.

Some of gpx viewer shows 4026km some apx. 4000. I ran every day without a rest day. The most distance I ran in a day was 83 kilometers. I was filming and taking pictures every day. I was tracked 24/7.
I was running with a GPS tracker. The average was almost 60 km a day in difficult terrain and through the mountains.
I checked all borders of my country Poland very exactly ;) It's a loop, first I ran left to Hel, which is counter-clockwise.
