The scene is set in a lush, green outdoor area. A cyclist wearing a black helmet and triathlon suit rides a bike on a sunny path, with a group of cyclists behind. The road is surrounded by greenery, and the rider appears focused and determined. Two athletes running on a sunny day. The man on the left wears a blue triathlon suit and cap with a number 324 bib.
