Starting from the leisurely alleys and painted walls of Dadu, riders catch the afternoon breeze and cruise along the Dadu River Sunset Bikeway. The camera captures the colorful rainbow arch bridge and levee scenery, stretching all the way to Lishui Fishing Harbor, where distant landmark chimneys and golden sunset glow interweave over the wetlands—a serene and healing sight. However, as the sky darkens, the tone shifts—the screen flashes 'Huanan Road No-Dismount Challenge Begins,' and everyone immediately switches gears to face the continuous steep climbs of the famous route 'Blue Highway.' Under the night lit by streetlights, this evening ride tests the riders' endurance, and the changing scenery along the way is truly captivating!
