The video shows a large crowd gathered near the starting line of an event, likely a race or marathon. The starting line is marked by a large, colorful arch with the word "CTAPT" (START) in Russian, along with the number 10 and logos of sponsors. Many participants are dressed in athletic wear and standing around, seemingly waiting for the event to begin. Some are taking photos or videos with their phones. There are tall flags with logos standing among the crowd. The weather is sunny and the sky is blue. Trees and buildings can be seen in the background.
