Physiological Demands and Load Management in Multi-Stage Road Cycling: Insights from Grand Tours and Stage Races

Multi-stage road cycling is a distinctive endurance setting in which prolonged daily exercise, repeated high-intensity efforts, variable terrain and limited recovery interact over several weeks. Grand Tours and other stage races expose riders to substantial external and internal loads, while fatigue, nutrition, sleep, illness risk and tactical demands may influence performance as strongly as maximal physiological capacity. Although power meters, GPS systems, heart-rate monitoring, biomarkers and wearable technologies have expanded access to competition data, important questions remain about how demands evolve across stages, how fatigue affects recovery and decision-making, and how physiological stress differs according to race situation, rider role, sex and competitive level. Existing research has improved the characterization of stage-specific power demands and training-load patterns, but findings are often based on isolated stages, individual riders or small samples. More integrated investigations are needed to connect longitudinal monitoring with performance, health and team strategy, and to clarify how field data can inform models of adaptation and competition.This Research Topic aims to advance understanding of the physiological demands, load-management practices and strategic decision-making processes that shape performance in multi-stage road cycling. It seeks to examine how external and internal loads accumulate across races; how riders recover and adapt between stages; and how training, nutrition, hydration, sleep and monitoring strategies can support performance while reducing the risk of injury, illness and overtraining. Contributions may also investigate how terrain, race context, rider specialty, team role and accumulated fatigue influence pacing, positioning, effort allocation and tactical choices. Comparative, longitudinal and modelling approaches are encouraged, particularly those linking individual physiological responses with team-level dynamics and race outcomes.To gather further insights in Grand Tours and other multi-stage road races, this Research Topic will focus on field-based and data-driven research across professional and developing athletes, while recognising the limitations of observational competition data and differences in race level, sex and team context. We welcome articles addressing, but not limited to, the following themes:Quantification of external and internal load during competitionPower profiles and effort characterization across stage typesFatigue accumulation, recovery kinetics and performance declineTraining, nutrition and hydration strategies across multi-day racesLongitudinal monitoring using heart-rate variability, biomarkers, sleep and wearable technologiesInjury, illness and overtraining preventionPhysiological and tactical differences between climbers, sprinters, time-trialists, domestiques, lead-out riders and general-classification leadersStrategic trade-offs in pacing, positioning and effort allocationTeam-level distribution of effort within stages and across a Grand TourDecision-making under accumulated fatigue, including late-race scenarios, descents and peloton dynamicsEffects of terrain, race context and competitive objectives on tactical choicesDifferences related to sex, competitive level and rider specializationComparative analyses combining case studies with population-level dataModelling and simulation approaches for translating race data into strategic recommendationsSubmissions may include original research, race-data analyses, reviews, perspective articles and case studies.
