Three men are running on a grassy trail outdoors, wearing race bibs and athletic gear. Trees and more runners are visible in the background on a foggy day. A group of runners, mostly men, stand closely together outdoors, wearing athletic gear and hydration packs. The focus is on a man with a mustache in a light gray cap, looking ahead with concentration. A man in athletic gear runs on a dirt path through a green field, surrounded by vegetation and trees. He wears a headband, backpack, race bib, and bright red running shoes. A small group of people stands on a grassy hilltop, with one person walking ahead, under a cloudy sky. The background showcases a misty, green landscape with distant trees and rolling hills, creating a serene and expansive view. A scenic landscape featuring rolling green hills dotted with shrubs and trees. A winding path cuts through the grassy terrain, leading towards the hill's summit. The sky above is cloudy, casting a serene light over the countryside.
