How to Find Your Optimal Cycling Cadence for Triathlon Racing

What Is Cadence and Why It Matters for Triathletes

Cadence is simply how many times your pedals go round per minute (RPM). It matters more for triathletes than for standalone cyclists because of what comes after the bike leg: the muscular fatigue you carry off the bike directly affects how your run feels. A cadence that’s too low, grinding a big gear, tends to load your quads harder and can leave your legs heavier for the run — even if it feels powerful in the moment.

Typical Cadence Ranges

• 60-70 RPM — low cadence, more force per pedal stroke, higher muscular load
• 80-90 RPM — the range most triathletes settle into for long steady efforts, balancing muscular and cardiovascular load
• 90-100+ RPM — higher cadence, shifts more of the workload onto your cardiovascular system and away from your muscles

How to Find Your Own Cadence

Most bike computers and smart trainers display cadence in real time, so the simplest approach is to ride a familiar route or a turbo session at a few different cadences — say 70, 85 and 95 RPM — at the same power or heart rate, and pay attention to which one feels most sustainable and which leaves your legs freshest afterwards. Over a few weeks of paying attention, most triathletes converge on a cadence somewhere in the 85-95 RPM range for race-pace efforts, though this varies with leg strength, bike fit and event distance.

Race-Day Cadence vs Training Cadence

For longer races — 70.3 and full-distance — a slightly higher cadence than you’d use for a short sprint bike leg tends to preserve your legs better for the run, since you’re relying less on muscular force and more on aerobic capacity over several hours. For shorter, punchier sprint and Olympic-distance racing where the run is shorter and you’re pushing harder overall, a slightly lower, more powerful cadence can work fine since leg freshness for the run matters less over a 5km than a half or full marathon.

Common Mistakes

• Copying a pro’s cadence numbers without accounting for your own leg strength and bike fit
• Changing cadence dramatically on race day rather than practising your race cadence in training
• Ignoring cadence completely and only ever looking at speed or power
• Grinding low cadence up hills purely out of habit rather than shifting to spin through the climb
