What’s the best cadence for endurance vs climbing?

Cadence is not about one magic number. It is a trade-off between muscular torque, cardiovascular load, and how your muscles fatigue over time. Understanding those trade-offs helps you choose a cadence that preserves your legs on long rides and keeps you steady on climbs.

The physiology behind cadence and torque

At any given power (watts), a lower cadence means higher force per pedal stroke. A higher cadence spreads that work across more revolutions with less force each time. This changes which muscle fibers you recruit and how you fatigue.

• Lower cadence (50–75 rpm): higher torque, more local muscular stress. You will recruit more fast-twitch fibers as torque rises, which can speed up peripheral fatigue.
• Higher cadence (85–100+ rpm): lower torque per stroke and smoother force application. Cardiovascular demand and oxygen cost rise slightly, but legs often feel fresher longer.
• Gross efficiency in lab tests often peaks around 60–80 rpm, yet trained cyclists self-select 85–95 rpm when riding hard because it reduces leg strain at meaningful power.
• As power and gradient increase, the optimal cadence tends to shift upward if gearing allows it.

Power (W) = Torque (N·m) × Angular velocity (rad/s)
Angular velocity = 2π × cadence(rpm) / 60

Body mass, crank length, pedaling skill, and terrain all modify what is optimal for you. Use these ranges as starting points, then personalize.

Endurance cadence: keep the legs fresh, not just the heart

For Zone 2 to Tempo (roughly 60–85% FTP), most trained riders are efficient and comfortable around 85–95 rpm on flat to rolling terrain. This range lowers torque per stroke while keeping heart rate stable. It also improves pedaling economy when you later ride at Sweet Spot or threshold.

• Target range: 85–95 rpm on flats; 80–90 rpm into headwinds or gentle rises.
• Signs you are in the right spot: steady breathing, stable HR, legs feel smooth rather than heavy, and you can hold the same watts late in the ride.
• When to adjust down: if HR drifts up >5 bpm at constant watts when you push above 95–100 rpm, drop to mid-80s.
• When to adjust up: if legs feel “pressy” at 70–75 rpm in Zone 2 and HR is low, increase to mid/high-80s to reduce torque per stroke.

Endurance cadence drills

• High-cadence skills: 3–4 × 8–10 min @ Zone 2, 95–100 rpm. Focus on relaxed hips and quiet upper body.
• Fast pedaling: 6–10 × 30–45 s @ 105–115 rpm in Zone 1–2 with full control, 60–90 s easy between. Stop before bouncing.
• Torque endurance: 3 × 10–12 min @ high Zone 2–low Tempo (70–80% FTP) at 70–75 rpm, seated and smooth. Builds resilience for rolling terrain.

Climbing cadence: gradient, gearing, and fatigue management

Climbing cadence depends on slope and gearing. Aim to keep torque reasonable on long climbs so your legs last. Modern gearing lets most riders hold 75–90 rpm on sustained grades if they choose appropriate cassettes and chainrings.

• Long climbs at Tempo to Sweet Spot (80–95% FTP): 75–90 rpm is a strong target for most riders.
• Steep ramps (>10%): 60–75 rpm may be unavoidable; sit tall, engage glutes, and avoid grinding through the dead spots.
• Seated vs standing: stand for 10–30 s to vary muscle recruitment and relieve contact points. Cadence will drop 5–10 rpm when standing—keep power smooth.
• Gearing tip: aim for at least a 1:1 ratio (e.g., 34×34 or 31×31). Many riders benefit from 11–34, 10–36, or subcompact fronts to keep cadence in the 80s on 8–10% grades.
• Knee comfort: if you get knee niggles, bias toward ≥75 rpm on longer efforts and avoid extended grinding below 60 rpm at high torque.

Climbing-specific workouts

• Low-cadence Sweet Spot: 4–6 × 5 min @ 88–92% FTP at 60–70 rpm, 3–4 min easy. Builds force application while controlled.
• Alternating cadence climbs: 2–3 × 12–15 min @ 88–92% FTP alternating 2 min at 75 rpm / 2 min at 90 rpm. Teaches you to manage torque and breathing.
• Threshold steady cadence: 2–3 × 8–12 min @ 95–100% FTP at your target climb cadence (80–90 rpm) to groove race-day rhythm.

Rule of thumb: on flats ride the highest cadence that keeps HR and breathing steady for the watts, and on climbs use gearing to stay mostly 75–90 rpm, dipping lower only when the slope forces it.

Find your personal optimum in two rides

1. Endurance day: do 3 × 8 min @ ~70% FTP on flat road at 70 rpm, 85 rpm, and 100 rpm (order randomized). Record HR, RPE, and note leg vs breathing strain.
2. Climb or trainer day: do 3 × 8 min @ ~90% FTP at 70 rpm, 80–85 rpm, and 95 rpm. Use the cadence that gives the best power stability with the lowest perceived leg strain.

If two cadences feel equal, choose the higher one for endurance and the midrange one for long climbs.
