The image is a collage of four photos of people participating in a trail running event. 

The first photo on the top left shows a woman running on a trail in the woods. She is wearing a blue t-shirt, black shorts, and a baseball cap. She appears to be in the middle of a race, as there are trees and bushes in the background.

In the top right photo, there is a man wearing a green beanie and a yellow reflective vest. He is standing on a wooden bridge with his arms raised in the air, as if he is cheering or celebrating. In the bottom left photo, two men are running on the bridge, one wearing a yellow shirt and the other wearing a gray jacket. The man in the yellow shirt is smiling and looking at the camera.
