Seedance 2.5 Mountain Bikers Race Downhill Sports Action Prompt

Ultra-photorealistic cinematic vertical video of an Olympic-level mountain-bike final featuring exactly two elite racers, one female and one male, competing head-to-head on a steep, technical downhill MTB course. Both riders launch together at full speed, aggressively navigating rugged rocks, exposed roots, loose gravel, steep drops, jumps, and muddy corners. The female racer takes an early lead, attacking technical sections with precise body positioning and controlled braking. The male racer closes the gap through a deep muddy corner, spraying dirt and water as both riders push their suspension and tires to the limit. They emerge side-by-side into the final section, sprinting aggressively toward the finish line. Final sequence: dramatic telephoto shot as both riders accelerate at maximum effort, handlebars nearly aligned, with the female racer crossing the finish line just a fraction of a wheel ahead of the male racer.
