The time trial is the most honest discipline in cycling: no drafting, no tactics, just you, the clock and the course. To win, you have to perfect a single skill — delivering the highest power you can just barely sustain over the distance, evenly, from the first minute to the last. That sounds simple, yet it is the most commonly botched art in amateur racing: most riders lose their time not on the climb or in the wind, but in the first five minutes, when they ride too fast. Here you will learn how time trial training works, what role threshold power, pacing and position play — and which sessions will make you measurably faster.

What makes time trialling different from every other discipline

In a time trial you start alone, drafting is forbidden, and there is no hiding behind others or letting a group do the work. That changes the physics completely: above roughly 30 km/h, air resistance consumes more than 90 percent of your total power — and it grows with the square of your speed, which means the required power grows with the cube. Going 40 instead of 35 km/h does not cost 14 percent more watts, but almost 50 percent more.

The key difference from road racing follows directly: there are no surges you can sit out and no recovery phases in the bunch. A time trial is one long threshold effort — the highest power your metabolism can hold in balance for the entire distance. Typical distances are 10 miles (around 16 kilometres, 20 to 30 minutes), 25 miles (around 40 kilometres, 50 to 70 minutes) or the bike legs of triathlons. The shorter the distance, the closer your race pace sits to — or slightly above — your anaerobic threshold.

That is exactly why time trial training is so plan-able: you know the target metric (power over the race duration), you know the bottlenecks (threshold power and aerodynamics), and both can be measured and trained precisely.

Threshold power: target metric number one

The single most important number for any time triallist is FTP — functional threshold power, the highest power you can hold for one hour. A 40-kilometre time trial is ridden practically at FTP, shorter ones at 105 to 110 percent of it. Every watt your FTP gains lands one-to-one on the stopwatch: five percent more threshold means roughly two to three percent less time on a flat 40 kilometres — over a minute in a 60-minute effort.

How to test your FTP reliably and derive your power zones from it is covered in detail in the article on the FTP test and power training. One particularity applies to time triallists: test your FTP in your aero position, not upright. Most riders produce three to eight percent less power on the aerobars than in a group position — a gap that only closes through targeted training in the race position. Feed your zones with an upright-tested FTP and you will overload yourself in every aero session.

The most efficient building block for FTP growth is sweet spot training: intervals at 88 to 94 percent of threshold deliver the highest adaptation per unit of fatigue — ideal when training time is limited. It needs easy base volume around it, following the 80/20 principle, because without an aerobic foundation your threshold stagnates after the first season at the latest.

Pacing: even beats heroic

The physiology of pacing is unambiguous: above threshold, your metabolism works disproportionately expensively. Riders who let their power swing wildly — attacking early, cracking, recovering — spend far more energy for the same average power than someone riding steadily. The best strategy on a flat time trial is therefore the most even power output possible from start to finish.

The most critical moment is the start. Fresh, full of adrenaline, with warm legs, 20 percent above target feels "right" for the first few minutes — and that is exactly where most riders lose their race. You repay the lactate debt from an overcooked start, with interest, over the rest of the distance. The proven counter-strategy: deliberately ride the first two to three minutes five to ten percent below your target, even if it feels slow. From minute five you are on target watts, passing the riders who started too fast.

Fine-tuning for wind and terrain: into a headwind and uphill you may sit five to ten percent above target; with a tailwind and downhill, correspondingly below. The reason is physics again — at lower speeds every additional watt buys more time than at high speeds. Pushing 250 instead of 230 watts uphill gains you more seconds there than the same 20 watts would cost you on the descent. Without a power meter, pace by heart rate and breathing rhythm: evenly hard but controlled breathing — if you are hyperventilating, you are going too fast.

Position and aerodynamics: the free speed

The second big lever costs no training hours at all: your position on the bike. A rider's drag coefficient (CdA) is around 0.40 upright on the hoods, about 0.32 in the drops and 0.25 to 0.28 on aerobars. At 40 km/h, moving from 0.32 to 0.27 saves roughly 30 to 40 watts — equivalent to two to three minutes over 40 kilometres. For comparison: achieving the same gain through training alone would take a well-trained rider one to two seasons.

The levers in descending order of effect per euro spent: aerobar setup and position first, then a tight-fitting skinsuit, then an aero helmet, and only then frame and wheels. More detail on the physics and the individual measures is in the article on cycling aerodynamics.

One warning that is often left out: the most aerodynamic position is useless if you cannot hold it. Riders who sit up after 20 minutes because their neck and lower back protest lose more than the extreme position ever gains. The best position is the most aerodynamic one you can hold at race pace for the full race distance — and that is exactly what you train: at least one session per week entirely on the aerobars, plus regular mobility work for hips and neck.

Four workouts that make time triallists faster

Two quality sessions per week are plenty — more intensity only costs recovery and lowers the quality of the key efforts. These four building blocks form the backbone:

  • Sweet spot: 3 × 15 to 20 minutes at 88–94 % of FTP, five minutes easy between efforts. The most efficient FTP driver — hard enough for maximal adaptation, sustainable enough for large total loads. The standard session for anyone short on training time.
  • Threshold intervals on the aerobars: 2 × 20 minutes at 95–100 % of your aero FTP, ten minutes rest. Trains threshold power and position tolerance at once — the most time-trial-specific workout there is. Maximum once per week.
  • Over-unders: 2–3 × 12 minutes alternating two minutes at 105 % and two minutes at 95 % of FTP, with no break inside the block. Teaches the body to clear lactate under load — exactly the skill that decides your pace through rollers and headwind sections.
  • Long ride with tempo blocks: three hours of base riding with 3 × 20 minutes at planned race pace woven in. Combines endurance with race specificity and trains fueling under load — for everyone racing longer time trials or triathlon distances.

The remaining sessions of the week stay deliberately easy. Riders targeting long events like a gran fondo benefit twice: time trial threshold is also the most important metric in gran fondo training, because it sets your sustainable climbing pace.

The five most common time trial mistakes

  • Starting too fast. The classic: the first five minutes twenty percent above plan, the last twenty minutes ten percent below. Always slower overall than riding evenly. Discipline at the start is the cheapest time saving there is.
  • Training in the group position, racing the time trial. If you do your intervals upright and have never tested your FTP in aero, you know neither your target watts nor whether you can hold the position on race day. At least one intensity session per week belongs on the aerobars.
  • Only short intervals, no volume. Five hard minutes feels productive but does not replace the aerobic base. Without enough easy hours, threshold stagnates — the 80/20 ratio applies to time triallists too.
  • Optimising equipment before the engine. The 5,000-euro wheels do almost nothing for a rider with an upright position and chaotic pacing. The order is: position, pacing, FTP — then equipment.
  • Rigid target watts in wind and hills. Grimly holding 230 watts uphill into a headwind invests your energy in the wrong place. The target is an average with deliberate deviations — plus into headwinds and on climbs, minus with tailwinds and on descents.

How Peakora plans your time trial training

Peakora anchors your entire cycling plan to your FTP: the structured sessions — sweet spot, threshold intervals, over-unders — come with concrete watt targets per interval, derived from your current threshold. After every session, the power you rode feeds into the load calculation, so fatigue and form are based on real numbers. And when your next FTP test comes back higher, the target watts of all upcoming sessions scale automatically — your plan grows with your performance instead of being stuck at last winter's level. Before your A-race, the engine builds in the taper automatically, so you arrive at the start line fresh.

Frequently asked questions about time trial training

How often should I do time-trial-specific training?

Two targeted sessions per week are enough — for example one sweet-spot and one threshold or over-under workout. The rest of your volume belongs to easy base riding. More intensity does not produce faster progress, only more fatigue that lowers the quality of your key sessions.

How much faster does a good aero position make you?

A lot: switching from an upright position to aerobars typically lowers your drag coefficient (CdA) from around 0.32 to 0.27 — worth roughly 30 to 40 watts saved at 40 km/h, or two to three minutes over 40 kilometres. No other single change delivers that much free speed.

Do I need a power meter for time trial training?

No, but it is the biggest training advantage you can buy. Without one you can pace by heart rate and feel, which works well once you know your target ranges. For race-day pacing, however, a power meter is almost irreplaceable because it shows output exactly, regardless of wind and gradient.

How long until time trial training pays off?

Expect noticeable improvements after four to six weeks of consistent twice-weekly quality training. A realistic gain is two to five percent more threshold power per eight-to-twelve-week block — plus the often larger gains from a better position and disciplined pacing.
