RIDING IN WIND: AERODYNAMIC STRATEGY, PACING BY POWER, AND THE MENTAL GAME OF HEADWINDS

By anthony-walsh

WHO THIS IS FOR

IS THIS YOU?

  • Experienced riders who want the aerodynamic science behind why headwinds cost so much energy and how to minimise drag
  • Cyclists who want to integrate power-based pacing strategy into windy training rides and races
  • Riders planning routes around prevailing wind direction to preserve glycogen and mental energy for the second half
  • Anyone racing or riding in groups who wants to master echelon mechanics and save 30-40 per cent of their energy in crosswinds

THE ROADMAN VIEW

The Roadman View

  • I've ridden with people who are far fitter than me but fall apart in wind because they refuse to adjust their pacing. The fittest rider in the group is not always the one who handles wind best — the smartest one is, and that's entirely learnable.
  • I remind myself of this on every windy ride: dropping your torso 10-15cm into a headwind saves 20-30 watts at the same ground speed. That's the difference between finishing a four-hour ride with legs and finishing it empty.
  • One thing I find fascinating is the mental cost of headwinds — riders produce 5-8 per cent less power in sustained headwinds, not because of physiology but because their brain inflates the perceived effort. Once I learned that, I stopped trusting my feelings in a headwind and just watched my power meter.

Every rider has a wind story. Mine involves a February morning on the coast road south of Dublin, 35kph gusts coming off the Irish Sea, and a three-hour ride that covered about 60 kilometres. My training plan said "endurance ride, zone 2." My speed said 19kph. My brain said quit.

I didn't quit. But I also didn't ride well. I ground a big gear into the headwind for two hours, watched my average speed with increasing misery, then turned for home with a tailwind that felt like cheating and legs that felt like concrete. The tailwind section should have been recovery. Instead I pushed harder because the speed finally looked respectable, and I finished the ride in a state that had nothing to do with zone 2 anything.

That ride taught me more about wind than any coaching manual could, because it showed me every mistake a rider can make in sequence. I've spent the years since then fixing those mistakes — in my own riding, and in the athletes I coach.

Here's the thing nobody tells you about wind: the fittest rider in the group is not always the one who handles it best. The smartest one is. Fitness is necessary. But in wind, intelligence multiplies fitness and ignorance divides it. The good news is that everything I'm about to describe is learnable, repeatable, and immediately applicable. You don't need to get fitter to ride better in wind. You need to ride differently.

The physics you actually need to understand

I'm not going to write a textbook chapter here. But there's one equation that changes how you think about wind forever, and you need to internalise it.

Aerodynamic drag scales with the cube of your speed relative to the air.

Let me break this down with real numbers. A rider producing 180 watts in still air might travel at 30kph. At that speed, their body and bike are pushing through air at 30kph, and the drag force is whatever it is. Now put a 20kph headwind into the equation. Same rider, same 180 watts, but the relative airspeed — the speed of air flowing over the rider — jumps from 30kph to 50kph. The drag force at 50kph relative airspeed is not 67 per cent higher than at 30kph. It is roughly 178 per cent higher. Nearly triple.

That is why a 20kph headwind doesn't feel like "20kph of extra difficulty." It feels catastrophic. Because the energy cost of pushing through the air at 50kph is in a completely different category from pushing through it at 30kph. Your power meter reads 180 watts. The air demands 280-300 watts for the same ground speed. Something has to give, and what gives is your speed. You slow from 30kph to somewhere around 22-24kph, and every fibre of your ego screams at you to push harder.

Here's where it gets really interesting. The inverse is also true — and this is the part most riders miss entirely. Small reductions in frontal area produce disproportionately large energy savings. Dropping your torso by 10-15cm doesn't save you a little bit of power. It saves 20-30 watts at moderate speeds. At higher speeds, the savings are larger still. That is the difference between finishing a four-hour ride in reasonable shape and finishing it destroyed.

Physics punishes the rider who fights the air. It rewards the rider who reduces the fight.

Body position: the cheapest watts you'll ever find

Position changes cost nothing. No new equipment. No extra training. No subscription. Just a willingness to get low when the wind gets up.

The headwind position

Hands on the drops, not the hoods. Elbows bent at roughly 90 degrees, not locked out straight. Back as flat as you can comfortably hold — you're aiming for your back to be roughly parallel to the top tube, not humped upward like a camel. Chin tucked toward the stem. Shoulders dropped and relaxed, not shrugged up around your ears.

You are not trying to hold a time trial position. That's a different thing, requiring a different bike and a different kind of suffering. What you're doing is reducing your frontal area by getting your torso lower and narrower. Think of your body as a wall facing the wind. Every centimetre you can shave off the height and width of that wall saves power.

The numbers matter. A rider sitting upright on the hoods with their chest catching the wind presents roughly 0.45 square metres of frontal area to the wind. The same rider in a tucked drops position might present 0.35 square metres. That 22 per cent reduction in frontal area, applied through the cube relationship with speed, produces savings of 25-40 watts depending on conditions. At race pace those savings are larger.

Sustainability beats perfection

Here's the coaching reality. A position you can hold for 10 minutes before your back screams at you is worse than a slightly less aggressive position you can hold for two hours. I see this constantly — riders go full tuck into the headwind, hold it for a quarter of an hour, then sit up because everything hurts, and spend the rest of the ride sitting upright because they've stiffened up.

Better approach: find the lowest position you can sustain for long periods. For most riders, that's hands on the drops, elbows moderately bent, back flat but not slammed. Practise holding it in training. Build duration gradually. A sustainable aero position is a skill, and it responds to practice like any other skill.

Crosswind position

Different problem. In a crosswind, the priority shifts from reducing frontal area to maintaining control. Hands on the drops for a lower centre of gravity. Elbows bent to absorb gusts — think of your arms as suspension. Weight centred over the bottom bracket, not leaning into the wind (lean the bike slightly into the wind while keeping your body more upright).

The critical thing: relax your grip. A death-grip on the handlebars means every gust translates directly into a steering input. A firm but relaxed grip lets your arms absorb the lateral force without yanking the front wheel off line.

Gear selection and cadence: stop grinding

The instinct in a headwind is to push a big gear. It feels like the right response — the wind is a force resisting you, so you apply more force back. This is wrong for a specific physiological reason, and understanding the reason will change how you ride in wind permanently.

When you grind a big gear at low cadence into a headwind, the torque demand per pedal stroke is high. That torque comes primarily from your Type II muscle fibres — the ones that generate force but fatigue quickly and recover slowly. Once you've fatigued those fibres, they don't come back on the same ride. You've burned matches that are gone.

When you spin a smaller gear at higher cadence — 85-95rpm versus the 75-80 that most riders default to in wind — you shift the demand toward your cardiovascular system. Your heart and lungs can sustain output for hours. Your fast-twitch fibres cannot. A higher cadence in a headwind costs slightly more in terms of cardiovascular load, but dramatically less in terms of muscular fatigue. The trade is always worth it.

Let me be really clear about this: shift down one or two gears from what feels natural, and spin. Your speed will be the same. Your effort will be the same. But your legs at the three-hour mark will be in a completely different state. Every rider I've coached through this adjustment reports the same thing — the back half of windy rides went from survival to sustainable.

Pacing by power: the tactical advantage that separates smart riders from fit ones

This is the core of the whole article. Everything else is supporting material.

In wind, speed is meaningless as a metric. It tells you nothing useful about your effort, your training load, or your tactical position. A 24kph average into a 25kph headwind at 200 watts is an entirely different ride from a 24kph average on a calm day at 140 watts, even though the number on the screen is identical. And a 28kph average into the same headwind at 260 watts looks faster but has buried you.

If you train or race with a power meter, set it as your primary display on windy days. Hide the speed field if you need to. Ride to the watts, not the kilometres per hour.

What this looks like in practice

Endurance rides: Hold your zone 2 power regardless of speed. If zone 2 is 170-190 watts for you, ride 170-190 watts whether that produces 30kph on a calm day or 21kph into a headwind. The training stimulus — the aerobic adaptation you're after — is identical. The speed is a consequence of conditions, nothing more.

Threshold intervals: Hit your target power, full stop. If your threshold is 260 watts, ride 260 watts. Into a headwind that might produce 28kph. With a tailwind it might produce 40kph. The training effect is the same. The watts are what matter.

Race pacing: This is where power-based pacing in wind becomes a genuine competitive advantage. In a road race or sportive with headwind and tailwind sections, riders without power meters tend to go too hard into the headwind (trying to limit their speed loss) and too easy in the tailwind (enjoying the free speed). This is exactly backwards. The physics of drag mean that extra watts into a headwind produce very small speed gains, while extra watts in a tailwind — where relative airspeed is lower — produce larger speed gains. The efficient strategy is to ease off slightly into the headwind and push slightly harder in the tailwind. But you can only execute that strategy if you're pacing by power.

Heart rate as a backup

If you don't have a power meter, heart rate is your next best tool. It's not as responsive — there's a lag of 30-60 seconds between effort change and heart rate change — but it's infinitely better than pacing by speed. Set a heart rate ceiling for the ride and respect it, regardless of what the wind does to your speed.

Echelons: the group riding skill that saves 30-40 per cent of your energy

Most riders understand basic drafting: sit behind the wheel in front, save energy. In a headwind, that works exactly as expected. The rider behind saves roughly 25-30 per cent of their energy by sitting in the slipstream.

Crosswinds change the geometry entirely, and this is where most riders lose enormous amounts of energy without realising it.

How echelons actually work

In a crosswind, the sheltered zone is not directly behind the rider ahead. It is offset to the lee side — the side sheltered from the wind. If the wind comes from the left, the sheltered zone is behind and to the right of the rider ahead. If you sit directly behind in a crosswind, you're exposed to the full force of the side wind and getting barely any draft benefit at all.

An echelon is a diagonal line of riders, each positioned in the wind shadow of the rider ahead and to the windward side. The formation fans diagonally across the road. The first rider takes the full wind. The second sits offset to the lee side, getting shelter. The third sits offset from the second, getting shelter from the second. And so on across the road.

The energy savings are substantial. A well-formed echelon in a strong crosswind saves each sheltered rider 30-40 per cent compared to riding alone. In a three-hour ride with sustained crosswinds, that's the difference between arriving with legs and arriving wrecked.

The rotation

In a working echelon, riders take turns at the front. The front rider, after their pull, peels off into the wind — not to the sheltered side, but into the wind. They drift backward along the windward side of the line, then slot in at the back on the sheltered side. The next rider is now at the front and the rotation continues.

This is counterintuitive. You pull off into the wind, not away from it. The reason: if you pulled off to the sheltered side, you'd block the sheltered lane for the riders behind you. Pulling off into the wind means the sheltered lane stays open and the rotation works smoothly.

Practical limits

Let me be honest about this. Full echelons require wide roads, a disciplined group, and practice. On a narrow road with oncoming traffic, a diagonal line stretching across the carriageway is dangerous and irresponsible. But the principle scales down. Even two or three riders can use echelon positioning in a crosswind — instead of riding single file, offset slightly to the lee side and share the effort. The savings are real even in a micro-echelon of three.

If you ride regularly with the same group, practise on wide, quiet roads. Start with three riders. Get used to the diagonal spacing, the rotation, the communication. Add riders as confidence builds. This is one of those skills that pays dividends every single windy group ride for the rest of your cycling life.

Route planning: make the wind work for you

Most riders plan routes around scenery, distance, and elevation. Very few plan around wind. That's a missed opportunity, because the sequence in which you encounter wind conditions has an outsized effect on how the ride feels and how well you perform.

The headwind-out, tailwind-home principle

If you have a choice, ride into the headwind in the first half and enjoy the tailwind home. This is not just about comfort — though comfort matters — it is about glycogen and mental energy.

In the first hour of a ride, your glycogen stores are full, your muscles are fresh, and your mental tolerance for discomfort is at its peak. That is the time to fight the headwind. By the time you turn for home, your stores are partially depleted, your muscles are fatiguing, and your brain is looking for reasons to ease off. A tailwind in the second half provides all of those: it reduces the physical demand and gives your brain the reward of higher speed when you need it most.

Riders who do the reverse — tailwind out, headwind home — often have a miserable final 90 minutes. The headwind hits when their resources are lowest, and the psychological impact of watching speed drop while fatigue rises is brutal. I've seen well-trained riders abandon rides not because they couldn't sustain the power but because the combination of fatigue and headwind broke their willingness to continue.

Using weather apps

Check the wind direction and speed before every outdoor ride. Not just whether it will be windy, but from which direction. Then design your route so the outbound leg faces into the prevailing wind and the return leg gets the tailwind. On out-and-back routes this is simple. On loops, angle the first half into the wind and the second half with it. You won't always get it perfect — wind direction changes, terrain affects local conditions — but even a rough alignment with this principle makes a noticeable difference.

The arithmetic of out-and-back wind rides

Here's something that trips up even experienced riders. On an out-and-back course, a headwind-out, tailwind-home ride always produces a lower average speed than riding the same course in calm conditions. Always. Even though you have a tailwind for half the ride.

The reason is time weighting. You spend more minutes riding slowly into the headwind and fewer minutes riding fast with the tailwind. The extra time at low speed drags the average down more than the reduced time at high speed lifts it up. This is not fixable with better pacing. It is a mathematical certainty.

The coaching takeaway: do not compare your average speed on a windy day with your average speed on a calm day. They are different rides under different conditions. Compare power. Compare heart rate. Compare how your legs felt at the end. Those are the metrics that tell you whether the ride was successful.

The mental game: perceived effort versus actual effort

This is the part that most coaching resources skip entirely, and it might be the most important section here.

Research into perceived exertion in headwinds shows a consistent pattern: riders produce 5-8 per cent less power in sustained headwinds than they do at the same RPE in calm conditions. Read that again. At the same perceived effort — the same feeling of how hard the ride is — riders produce measurably less actual power when facing a headwind.

This is not a fitness problem. It is a perception problem. Your brain processes multiple inputs when calculating "how hard is this": power output, heart rate, breathing rate, muscle fatigue, and — critically — visual speed feedback and the sensation of wind on your face. In a headwind, two of those inputs scream "this is hard" regardless of your actual power: you're going slowly and you can feel the air resistance on your body. Your brain integrates those signals and concludes you're working harder than you are. So it dials back your output to match what it thinks is a sustainable effort.

How to counteract it

First, know it's happening. Awareness alone is worth half the battle. When you're riding into a headwind and it feels like threshold effort, check your power. There's a strong chance it's 10-15 watts below your actual threshold. The feeling is not lying exactly, but it's not telling you the whole truth either.

Second, use external metrics to override internal sensation. This is exactly what a power meter or heart rate monitor is for. Your brain says "I'm at 90 per cent effort." Your power meter says "you're at 82 per cent of threshold." Trust the power meter. You have more in the tank than your brain wants you to believe.

Third, break the headwind into segments. Sustained headwinds are mentally corrosive because they feel endless. Give yourself landmarks: the next junction, the next turn, the next kilometre marker. Ride to the next one. Then the next. Segment the effort and the mental load shrinks.

Fourth — and this is the technique I come back to more than any other — treat the headwind like a climb. You would not look at a 6 per cent gradient and expect to hold flat-road speed. You would accept the gradient, ride to your power, and judge the effort by the effort itself. A headwind is a gradient made of air. Accept the speed it gives you. Ride to your watts. Judge the ride by the numbers that matter.

Tailwind discipline: the mistake nobody thinks they're making

Tailwinds feel like gifts. Your speed is up, your effort feels easy, everything is flowing. And because everything feels good, your discipline falls apart in one of two predictable ways.

The coasting trap. Tailwind speed makes the ride feel fast, so you back off the power. Your zone 2 target is 180 watts, but you're cruising at 155 watts because the speed looks right. You're training your aerobic system at a lower intensity than intended. The ride is junk training disguised as a good session.

The push trap. The opposite problem. Tailwind speed makes you feel strong, so you push harder than prescribed. Your zone 2 target is 180 watts, but the tailwind has you feeling brilliant so you ride at 200. For 90 minutes. Then you turn around, the headwind hits, and those 90 minutes of over-target effort have depleted your glycogen and fatigued your legs for the section of the ride that demands the most from both.

The fix for both: pace by power, the same as in a headwind. Hold your target watts. Let the tailwind do whatever it does to your speed. If you're in zone 2, stay in zone 2. If you're doing sweet spot intervals, hold sweet spot watts. The tailwind is a condition, not a performance metric.

When to use tailwinds strategically

There is one scenario where tailwinds are a genuine training asset: high-speed neuromuscular work. A tailwind lets you reach 45-50kph at moderate power outputs, which gives you a chance to practise pedalling smoothly at high cadence and high speed. Spin-ups, leg-speed drills, and race-speed simulations are all easier and safer with a tailwind assisting. If your route has a tailwind section and your session includes any neuromuscular work, put it there.

For structured interval sessions, plan your hard efforts for the headwind or sheltered sections where conditions are predictable, and use the tailwind section for recovery intervals. The wind assistance during recovery lets you spin at a decent speed while actually resting, which is both more pleasant and more effective than crawling along recovering into a headwind.

Putting it all together

Wind is the condition that most clearly separates coached riders from self-coached riders. Not because coached riders are fitter, but because they've been given a framework for handling conditions that most riders just suffer through on instinct.

That framework, in short:

  1. Understand the physics. Drag scales with the cube of relative airspeed. Small position changes produce large energy savings. Fighting the air is always less efficient than reducing the fight.

  2. Get low when it matters. A sustainable aero position in a headwind is worth 20-30 watts. Practise it until it's automatic.

  3. Spin, don't grind. Higher cadence, lower gear. Move the load from fast-twitch fibres to the cardiovascular system.

  4. Pace by power, always. Speed is a consequence of conditions. Power is a consequence of effort. One of those is useful. The other is noise.

  5. Learn echelon basics. Even a three-rider echelon in a crosswind saves real energy. The skill pays for itself on every group ride in wind.

  6. Plan your route. Headwind out, tailwind home. Fresh legs for the hard work, assisted legs for the way back.

  7. Know your brain is lying. Perceived effort in headwinds overestimates actual effort. Use your meter to stay honest.

If you want to go deeper on any of this — pacing strategy, position work, race tactics in wind — the Roadman Cycling community on Skool is where those conversations happen daily. Riders and coaches breaking down exactly this kind of detail, with power files and real-world data to back it up. No fluff. Just the work.

Wind doesn't go away. But your relationship with it can change completely. And it starts with the decision to stop fighting and start thinking.

FAQ

FREQUENTLY ASKED QUESTIONS

How many extra watts does a headwind cost?
A 20kph headwind can increase the power required to maintain 30kph from roughly 180 watts to 280-300 watts, depending on rider size and position. The relationship is cubic — doubling relative wind speed roughly doubles the drag force, but because drag force scales with velocity squared and power scales with velocity cubed, even moderate headwinds impose a large energy penalty.
Should I use deeper wheels in crosswinds?
Deep section wheels catch crosswinds and make the bike harder to control in gusts. If sustained crosswinds above 30kph are forecast, swap to shallower rims — 40mm or less — or at minimum put the deeper wheel on the rear where crosswind-induced steering is less dangerous.
What cadence should I use in a headwind?
Increase cadence by 5-10rpm above your normal self-selected rate. A higher cadence in a headwind reduces the torque demand per pedal stroke, which delays muscular fatigue. Grinding a heavy gear into wind feels productive but costs you in the second half of the ride.
Is it worth riding in very strong wind or should I train indoors?
Sustained winds above 50kph or gusting above 65kph make road cycling dangerous for most riders. Below those thresholds, windy rides build bike-handling confidence and mental resilience that no indoor trainer can replicate. The key is adjusting your expectations — go by power and heart rate, not speed.
How do you ride an echelon in a crosswind?
Position yourself to the sheltered side of the rider ahead — if the wind comes from the left, you sit to their right, slightly behind and offset. The group fans diagonally across the road. Riders rotate through the front, pulling off into the wind, then drifting back down the sheltered side. It requires communication and practice but saves enormous energy.

DOES AERO MATTER FOR AMATEURS? WHAT THE SCIENCE ACTUALLY SAYS | ROADMAN CYCLING PODCAST

Aero gets sold as free speed for pros, time triallists and triathletes — but does it matter for the everyday rider doing club runs and sportives? This solo episode cuts through the marketing. Your body, not your bike, makes most of the drag, which means the biggest gains are the cheapest ones: how you sit, how you hold the bars, and whether your kit actually fits. Here's when aero is real free speed, when it's expensive nonsense, and the $0 changes worth making first.
