Downhill course: typically 400-600 m public street or park slope; substantial gradient (8-15%) for adequate gravity acceleration; Course features: jumps (one or more ramps for theatrical air-time), obstacles (hay bales, tire walls, sometimes water hazards), tight turns + chicanes; Padded crash ba...
Why people argue about this
People often assume that the course length is strictly 400-600 meters without considering other factors like gradient and obstacles, leading them to believe they can just make a shorter but steeper downhill track instead of adhering to the full specification.
