A vibrant, 8K, highly detailed image of a beautiful brunette riding a mountain bike on a forest trail in the mountains. She is wearing black spandex biking shorts, black biking shoes, a thin lightweight half shirt with no sleeves and her midriff showing. Her hair is up in a loose bun and some of her hair is hanging down and cleaning to her sweaty face. She is sweating a lot from the ride. It is a beautiful mountain scene with the forest in it's autumn colors, a big lake and low, wispy clouds.
