Cadence — the number of pedal revolutions per minute — is one of the most discussed variables in cycling training, and one of the most misunderstood. The popular advice to spin at 90+ RPM as a universal efficiency prescription is partially supported by research, but the full picture is considerably more nuanced. Optimal cadence is individual, terrain-dependent, and fitness-state-specific — and understanding the physiology behind it allows you to make evidence-based cadence choices rather than following generic targets.
At any given power output, you can achieve your wattage through an infinite combination of cadence and force per pedal stroke. A rider producing 250 watts can do so at 60 RPM with high force per stroke, or at 100 RPM with low force per stroke. These two approaches tax the body's energy systems very differently — and understanding that difference is the foundation of cadence optimisation.
The Physiology: Cardiovascular vs Muscular Load
Higher cadence at a given power output shifts muscular demand away from large, forceful contractions and distributes effort across a faster, lighter stroke pattern. The trade-off: cardiovascular demand (heart rate and oxygen consumption) increases with cadence. Lower cadence concentrates muscular force into fewer, more powerful contractions — efficient from an oxygen-cost perspective, but demanding on muscle fibres and increasing peripheral fatigue over prolonged efforts. Research by Lucia et al. (2001) examining Tour de France competitors found preferred climbing cadences of 88–98 RPM — substantially higher than biomechanically optimal cadences from metabolic efficiency models — suggesting elite cyclists self-select cadence to protect muscular fatigue during prolonged events rather than to minimise oxygen cost per watt.
What Research Shows About Optimal Cadence
Studies measuring gross mechanical efficiency (oxygen cost per watt) consistently identify optimal cadence at 60–80 RPM — lower than what most trained cyclists prefer. However, studies measuring performance in prolonged events (90+ minutes) favour higher cadences of 85–100 RPM, because metabolic efficiency in isolation does not account for the fatigue distribution benefits of spinning faster. The practical consensus for trained endurance cyclists:
- Flat terrain at moderate intensity: 85–95 RPM optimises the cardiovascular-muscular load balance for most athletes
- Climbing at sustained efforts: 70–85 RPM allows greater force application with lower cardiovascular demand — particularly relevant on long climbs above 8% gradient
- Short, high-intensity efforts (sprinting, surges): 95–110+ RPM reduces peak muscular recruitment and allows faster power delivery
- Triathlon and time trial: 85–95 RPM preserves leg muscle freshness for the run — the primary motivation for high cadence in multi-sport racing
Cadence Drills for Efficiency Development
Improving your ability to spin efficiently at higher cadence takes deliberate practice. Key drills to incorporate 1–2 times per week within endurance rides:
- Single-leg drills: Unclip one foot and pedal with the working leg for 30-second intervals. Develops a smooth, round pedal stroke by eliminating the dead spot at the top and bottom of the revolution.
- High-cadence spin intervals: 6×1 minute at 110–120 RPM in a light gear at low wattage, with 2 minutes easy recovery between. Develops neuromuscular efficiency at high RPM without cardiovascular stress.
- Cadence pyramids: Start at 70 RPM and increase by 5 RPM every 2 minutes up to 100+ RPM, then descend back. Builds a broad cadence range and improves proprioceptive awareness across the full spectrum.
Cadence and Fueling for Long Rides
Higher-cadence cycling increases glycolytic demand slightly compared to lower-cadence cycling at the same wattage — meaning carbohydrate requirements are marginally elevated when spinning fast for extended periods. Athletes targeting 90+ RPM in sportives or triathlon should plan fueling at the higher end of the 60–90g/hour carbohydrate recommendation for rides exceeding 2 hours. NorthLine performance gels deliver 22g of dual-transporter carbohydrates per serving, designed to be absorbed at the maximum rate your intestinal transporters allow regardless of exercise intensity or cadence.
