Observational study of 36 male professional cyclists in the 2020 Vuelta a España, categorized as climbers (n = 13), all-rounders (n = 13), and flat specialists (n = 10). Power meter data from 17 stages (3 flat, 9 semi-mountainous, 5 mountain) were analyzed using principal component analysis and mixed models to assess changes across stage progression (0%-100%). Climbers showed high initial high-intensity power in mountain stages, decreasing by 40.70 W per 10%, with average power increasing by 8.45 W per 10%. All-rounders' average power increased by 0.25 W per 10% in mountain, 0.03 W in semi-mountainous, and 10.40 W in flat stages. Flat specialists' average power increased by 0.26 W in mountain, decreased by 0.04 W in semi-mountainous, and increased by 9.29 W in flat stages. Mountain stages had high initial intensity with efficiency rising by 0.02 per 10%; semi-mountainous stages showed mixed patterns; flat stages had power increases of 9.29-10.40 W per 10%. Workload varies by role and stage, offering insights for targeted training and tactics in Grand Tours.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/DeporteFenómenos BiomecánicosRendimiento Atléticojournal article10.1002/ejsc.70170open accessFisiología humanaDeporteAnálisis de datosGoal 3: Ensure healthy lives and promote well-being for all at all ages
