After the first kilometer. Because it was my first marathon, I had decided to be one of the latest at start, then I was slowly outrunning other runners.
Before the food point in Dargomysl, 4.7 km.
The end of the first lap - Debno, I had just passed 14 km (white table at the back) and outrun a bigger group of runners.
The beginning of the second lap (a few hundred meters farther, I run in the opposite direction). Two places before me a runner who had sped up significantly and had outrun me (at the previous photo he was covered by me).
