Cycling is the discipline in which set-up matters more than movement. The bicycle constrains the athlete's joints to a fixed path, so most of what would be called technique in swimming or running is here decided by geometry: where the saddle sits, how far away the bars are, how long the cranks are and where the foot is fixed on the pedal. Get those right and the rider's remaining job is largely about intensity discipline, gear selection and holding a position for hours.
Position: three contact points and one compromise
A rider touches the bicycle at the saddle, the pedals and the bars, and every fitting decision is a trade between three things that pull in different directions — power, comfort and aerodynamics. On a long ride, comfort is power, because a position that cannot be held is a position that will be abandoned in the last hour.
The saddle governs almost everything downstream. Its height sets the range through which the knee travels; its fore-aft position sets where the foot is relative to the pedal spindle at the top of the stroke, and therefore how the load is shared between the quadriceps and the posterior chain. Saddle height in particular has measurable consequences for both loading and performance, discussed further in bike fit and pedalling analysis.
Reach and drop to the bars govern the trunk angle. A lower front end reduces frontal area — the dominant resistance above roughly 25 km/h — but costs hip angle, and a hip angle that is too closed limits the ability to drive the leg down at the top of the stroke. This is why a position optimised on a static fitting can fail on a four-hour ride: the athlete's hip flexibility, not their power, becomes the limit.
The pedal stroke, by sector
It is useful to think of the crank circle in four sectors, because the muscular contribution differs sharply between them.
- Top (11 to 1 o'clock) — the transition over the top. The foot should move forward across the top rather than pressing down early into a crank that has no leverage.
- Downstroke (1 to 5 o'clock) — where nearly all propulsive force is produced, by hip and knee extension.
- Bottom (5 to 7 o'clock) — the transition through the bottom, where the ankle allows the foot to move rearward rather than continuing to push into the ground.
- Upstroke (7 to 11 o'clock) — the recovery. The trained rider unweights this leg; they do not actively pull it up.
The last point is where popular advice most often misleads. Deliberately pulling up through the upstroke is not what strong riders do, and coaching it does not reliably improve efficiency. The study of the relationship between cadence, pedalling technique and gross efficiency found that the pedalling pattern associated with the best efficiency is not the one that most evenly distributes force around the circle. What is worth eliminating is a leg that rests its weight on the rising pedal, because that is a genuine cost the other leg has to pay.
Cadence
Trained cyclists habitually choose a cadence higher than the one that minimises oxygen cost at a given power. This is not a mistake. Work on cycling efficiency and pedalling frequency in road cyclists shows the most metabolically economical cadence sitting well below the self-selected one, and the reason for the gap is force: a higher cadence produces the same power with less force per stroke, which spares the muscle and, for a multisport athlete, spares the legs for what comes afterwards.
The practical guidance is a range rather than a number. Most endurance riders settle somewhere in the eighties to low nineties on the flat, dropping on climbs where gearing runs out. What matters more than the exact figure is that the rider can operate comfortably across a range, because terrain will not respect a preferred cadence.
Gearing and shifting
Gear selection is intensity management by another name. The most common error on a hilly ride is shifting late — waiting until the gradient has already forced the cadence down and the effort up — which turns a steady ride into a series of unplanned intervals. Shifting early, before the gradient bites, keeps cadence and effort roughly constant, which is the whole point of gears.
On a long event, the discipline of not exceeding the intended intensity on short climbs is worth more than any equipment choice. The cost of a hard two-minute climb is not paid in those two minutes; it is paid later, and disproportionately, which is the subject of judging training intensity.
Handling, and handling when tired
Bike handling is a trained skill that endurance athletes systematically neglect because it does not appear in any fitness metric. Cornering with the outside pedal down and weight through it, braking before the corner rather than in it, holding a line while looking behind, drinking and eating without deviating — all of these are ordinary and all of them degrade markedly with fatigue.
The place to practise them is on easy rides, at low speed, deliberately. On a long ride they are also a safety matter rather than a performance one: most of what goes wrong late in a long day goes wrong because attention and coordination have quietly declined. The longer race distances make that decline the central problem of the discipline.
