Understanding load structure helps optimize training. # The Load Structure of Competition Climbing: What Data Reveals What exactly happens during a climbing competition? Researchers analyzed international competitions to quantify the physical demands of each discipline. The data provides precise training targets for competitive climbers. ## Study Approach Scientists analyzed video footage and timing data from international lead, boulder, and speed climbing competitions. They measured move counts, hold types, wall angles, timing, and rest intervals. ## Lead Climbing Load Structure **Route Characteristics** Average route height: 15 meters. Average number of hand moves: 40-50 moves. Typical time on route: 4-6 minutes. Wall angle distribution: approximately 30% vertical, 50% moderate overhang (up to 30 degrees), and 20% steep overhang (over 30 degrees). **Hold Types Used** The most common hold types were crimps (40% of holds), slopers (25% of holds), pinches (15% of holds), and jugs/rest holds (20% of holds). **Intensity Pattern** Lead routes typically follow a specific pattern. The lower section uses moderate holds with higher density, the middle section has crux moves with harder holds, and the upper section features increasingly difficult moves when athletes are fatigued. **Rest Opportunities** Rest positions appear roughly every 8-12 moves. Average rest duration: 5-15 seconds. Quality of rest positions decreases as routes progress. ## Bouldering Load Structure **Boulder Characteristics** Average number of moves: 4-8 moves per boulder. Typical attempt time: 15-45 seconds. Number of boulders per round: 4-5 problems. Rest between attempts: 4-5 minutes maximum. **Move Types** Boulders feature higher proportions of dynamic movements (40-60% of moves), coordination-intensive sequences, and powerful individual moves. **Hold Types** Boulder holds tend toward volumes and features (35%), slopers (25%), crimps (20%), and pinches and unusual grips (20%). **Energy Demands** Short, maximum-effort attempts. [High proportion of anaerobic energy contribution](/blog/climbing-specific-tests-energy-systems). Significant power demands on individual moves. Brief recovery between attempts. ## Speed Climbing Load Structure **Route Specifications** Standard route height: 15 meters. Fixed hold configuration. World-class times: under 6 seconds. Move count: approximately 20 hand moves. **Physical Demands** Maximum power output throughout. Precise, rehearsed movement sequence. Minimal margin for error. Pure anaerobic effort. **Training Implications** Speed climbing requires specific power development, route-specific practice, and reaction time training. ## Training Recommendations Based on Load Structure **For Lead Climbers** [Train for 4-6 minute sustained efforts](/programs/arc-training-endurance). Practice on varied angles with emphasis on moderate overhangs. Develop capacity for 40-50 move routes. Include specific crimp and sloper training. Practice utilizing rest positions efficiently. **For Boulder Competitors** Focus on maximum power and dynamic movement. Train short, high-intensity efforts with adequate recovery. Develop diverse grip strength including unusual positions. Practice problem-solving under time pressure. Build anaerobic capacity for repeated attempts. **For Speed Specialists** Maximum power development. Route-specific practice to automatize movement. Reaction time and start technique. Consistency under competitive pressure. ## Periodization Insights **Competition Season** During competition phases, training should match competition demands closely in terms of duration and intensity. Include competition simulations. Reduce overall volume while maintaining intensity. [Practice competition-specific recovery between attempts](/blog/recovery-after-climbing-competition-elite). **Preparation Phase** Build capacity exceeding competition demands. Higher volume, more varied training. Address weaknesses identified in competition analysis. ## The Combined Format Challenge Since the 2021 Olympics introduced combined competition (lead, boulder, speed), athletes face unique challenges. Training must address all three energy systems, technique demands vary dramatically between disciplines, and periodization becomes complex. The data suggests that successfully competing in combined requires building a broad base of fitness, then specializing sessions for each discipline. ## Practical Applications **Analyze Your Competitions** Film and review your competition performances. Compare your move execution to elites. Identify where you lose time or fall. **Match Training to Demands** Use the load structure data to design workouts that replicate competition conditions. Train at competition-relevant intensities. **Prepare Mentally** Understanding typical demands helps with pacing strategy, energy management, and mental preparation. ## Limitations **Competition Evolution** Route setting styles and hold types change over time. Data represents a snapshot of competition demands at the time of analysis. **Individual Variation** Elite athletes may experience routes differently based on height, style, and strengths. Load structure provides averages, not individual prescriptions. --- *Based on: Winkler M, Kunzell S and Augste C (2022) The Load Structure in International Competitive Climbing.
