XCO round: single-mass-start, 4-7 laps, 80-100 min target winning time; XCC (short track): separate short-track race on Friday, used for XCO grid seeding Sunday; DHI round: seeding run + finals run; fastest aggregate time wins
Why people argue about this
People often assume that in a single-mass-start format, riders start one after another, which leads them to misunderstand how the UCI Mountain Biking World Series operates. Actually, it's structured so all riders start together and race simultaneously over 4-7 laps with a time limit of 80-100 minutes for each round, creating chaos if they think individual starts are happening instead.
