Runners already know what cadence is. They just don't call it that.
Anyone who has read about running form has heard the number 180 — steps per minute, the widely cited target for efficient turnover. It's not a rule carved in stone, but the underlying logic is sound: quick, light steps beat long, forceful, ground-crushing strides for both efficiency and injury risk. Cycling has the exact same idea, measured the exact same way, and most runners arrive on a bike and ignore everything they already know about it.
What cadence actually is
Cadence is how many times per minute the pedals complete a full revolution — one foot down, then the other, counted as revolutions per minute, or rpm. Every bike computer and head unit shows it. Most riders glance at the number occasionally and never think about it again, which is a mistake, because cadence is one of the few variables you can change instantly, mid-ride, with nothing but a gear shift.
It matters for two connected reasons: efficiency and injury prevention. Pedal at the wrong cadence for long enough and you're either burning through muscle glycogen unnecessarily or asking your knees to handle load they don't need to carry. Get it into a sensible range and both problems mostly disappear.
The running analogy that makes this obvious
Running coaches prescribe roughly 180 steps per minute for the same reason cycling coaches target 85 to 95 rpm: both prioritise efficient turnover over brute force per stride or per pedal stroke. A runner taking long, slow, pounding strides is loading each footstrike harder than necessary and taking longer to recover between them. A cyclist grinding a low cadence is doing the direct equivalent — loading each pedal stroke harder than necessary, with less time for the muscle to recover before the next one.
Runners already believe this, in their sport. The translation to cycling is not a new philosophy. It's the same idea, different equipment.
Why runners grind too low a cadence when they start
Here's the pattern I see constantly with runners taking up cycling: they select a bigger gear than they need, pedal at what feels like a purposeful, muscular 55 to 65 rpm, and mistake the burning quads for a good workout.
It's an understandable mistake. Runners are used to a sport where effort translates fairly directly to force — you push off the ground harder, you go faster, and hard efforts feel like muscular work. Bring that instinct to a bike and the pedals start to look like a leg press: pick a heavy gear, grind it out, feel the burn, assume that's the point.
It backfires in three specific ways. First, it overloads the quads specifically, because a low cadence in a hard gear asks the biggest muscle group to produce most of the force with minimal help from momentum. Second, it burns through glycogen faster than a higher-cadence approach at the same power output, which matters on anything longer than an hour. Third, and this is the one that should get a runner's attention, it creates exactly the kind of repetitive knee stress under load that mirrors problems runners may have been trying to get away from in the first place. None of that is necessary. It also spikes heart rate for reasons that have nothing to do with fitness — the body working harder than the intended effort justifies, simply because of how the force is being applied.
The 80-95 rpm sweet spot
For most recreational riders, 80 to 95 rpm is the efficient operating range, and it's worth understanding why rather than just accepting the number.
Cadence determines where the workload gets distributed. Pedal at a low cadence — 60 to 75 rpm — and more of the work lands on the muscles: quads, glutes, calves, doing bigger, slower contractions to produce the same power. Pedal at a higher cadence — 95 rpm and above — and more of the work shifts to the cardiovascular system: heart rate climbs, breathing gets harder, but the muscular tension per pedal stroke drops.
Neither end of that spectrum is wrong in isolation — track sprinters and time trial specialists use very different cadences for very different reasons. But for a runner arriving at cycling, the choice is close to obvious. You already have a well-trained aerobic engine from years of running. You do not yet have cycling-specific muscular endurance in the quads and hip flexors the way you have it in your calves and hamstrings from running. Starting at 85 to 90 rpm means you're using the system that's already strong — your heart and lungs — instead of leaning on muscles that haven't done this specific work before.
It will feel strange initially. Spinning at 90 rpm feels almost frantic to someone used to a longer, more deliberate stride pattern, and the instinct is to slow down and "settle in" to something that feels more controlled. Resist that instinct for the first month. The higher cadence is doing you a favour even when it doesn't feel like it.
Cadence and heart rate: the trade-off explained
At matched power output — meaning you're producing the same number of watts either way — a higher cadence produces a higher heart rate than a lower cadence, but lower muscular fatigue. This confuses a lot of new riders, who look at a lower heart rate while grinding a big gear and assume that's the "easier," more efficient way to ride.
It isn't. The lower heart rate at low cadence is masking where the cost actually went: into the muscles, as tension and fatigue that doesn't show up on a heart rate strap and instead shows up an hour later as heavy, unresponsive legs, or the next morning as soreness that has nothing to do with how far you rode. For a runner, whose cardiovascular system is already the strongest part of their engine, using it — accepting the slightly higher heart rate that comes with a higher cadence — is the trade worth making rather than fighting.
Gears, briefly: how to actually change your cadence
If cadence is new territory, gears are the tool you use to control it, and the concept is simpler than it looks. A smaller gear (easier to pedal, lower resistance) lets you maintain a higher cadence at a given speed. A bigger gear (harder to pedal, more resistance) drops your cadence at that same speed unless you produce more force per stroke.
The habit worth building immediately: when your cadence drops below about 80 rpm on flat ground or a gentle climb, shift to an easier gear rather than grinding through it. This is "spinning" versus "grinding" — spinning being a quicker cadence in an easier gear, grinding being a slower cadence in a harder gear producing the same speed. Spinning is very nearly always the better default for a new rider.
One equipment note that matters more than people expect: if you're buying or renting a bike, a compact crankset — smaller chainrings up front — gives you easier low gears than a standard crankset. For a beginner, particularly one still building cycling-specific strength, compact is almost always the better choice. It costs you nothing on flat ground and saves your knees on the climbs.
Three drills to build a smooth pedal stroke
Single-leg focus drills. On a stationary trainer, unclip one foot and rest it on a support or the frame, then pedal with the other leg alone for 30 to 60 seconds before switching. This exposes the dead spots in your stroke — the points where you're not actually producing power — and forces you to pedal in circles rather than just pushing down. Uncomfortable at first. Remarkably effective within a few sessions.
Spin-ups. On flat ground or the trainer, gradually increase your cadence every 20 seconds — 80, 90, 100, 110 rpm and beyond — without bouncing in the saddle, then ease back down over the same steps. Repeat four to six times. This builds the neuromuscular coordination for a smooth stroke faster than almost anything else, because it forces your legs to find efficient movement patterns at speeds your muscles haven't been asked to move at before.
Sustained cadence holds. Pick a moderate, sustainable effort and hold exactly 95 rpm for five-minute blocks, resting two to three minutes between them, for three or four repetitions. Unlike spin-ups, this trains your ability to hold an efficient cadence under fatigue, which is what actually matters once you're two hours into a ride and your form wants to fall apart.
The habit that pays off
None of this requires new equipment or a big time commitment — it's a habit shift, glancing at the cadence number on your computer and making small gear adjustments to keep it in range, the same unconscious correction a runner makes to their stride without thinking about it. Give it a few weeks and it stops being a number you have to check and becomes the way you naturally ride.
If you want structured sessions that build this alongside the rest of your engine, rather than guessing at drills on your own, come find the riders doing exactly this inside the Roadman community — plenty of them made the same jump from running and can tell you what actually worked.
