How to Prepare for a Ramp Test — the 24 Hours Before Your FTP Test

The ramp test is short but merciless: you can't ride it on tactics, and any lack of freshness shows up straight in the watts. The good news — preparation is simple and fits into 24 hours. Here's the plan that makes your result reflect fitness, not fatigue.

48–24 hours out: freshness above all

Tired legs are the most common cause of a deflated result — they can take away 10–20 W. The rules:

• Day before the test: rest or easy spinning in zone 2 for up to 45–60 minutes, ideally with two or three short openers (30 s) so your legs aren't "wooden".
• Two days out: no threshold intervals and no leg day in the gym. Sore legs and an FTP test are mutually exclusive.
• Sleep. One bad night lowers your maximal power more than many a head cold. If the night was rough — postpone the test; nothing bad happens.

Test day: food, caffeine, timing

• Last proper meal 2–3 hours before the test. Carbs, no experiments. Testing on a full stomach ends in nausea during the final minutes.
• Caffeine works — an espresso or a caffeinated gel 30–45 minutes before the test boosts performance and pain tolerance. But: if you don't drink coffee daily, don't start on test day.
• Test at the same time of day you normally train. Your body in the morning and in the evening are two different engines; comparability between tests beats the theoretically "best" hour.

The setup: cooling is free watts

On a trainer with no airflow you overheat several times faster than on the road, and overheating cuts power exactly in the test's finale — the part that decides your result.

• A fan is mandatory, ideally two: one on the torso, one on the face and head. The cheapest watts you'll ever buy.
• A cool room — open the window, test before the room heats up.
• Towel and bottle within reach; a sip of water between steps is fine.
• Check your equipment before starting: trainer calibration (spindown) or power meter zero-offset, charged batteries, stable pairing. A dropped connection in minute 18 voids the whole test.

Cadence and gearing: decide before you start

In ERG mode the trainer holds the target power regardless of gear — but cadence is yours to manage:

• Hold 85–95 rpm from the start. As the load rises, a falling cadence pulls you into the "ERG spiral": slower revs → more torque required → even slower revs → the test ends before your legs do.
• Pick a middle gear and don't shift during the test — shifting in ERG jerks the resistance.
• When it gets hard, watch your revs, not the power. The trainer controls power; your only job is cadence.

Headspace: the finale is a negotiation

The ramp test ends in failure — by definition. The difference between a good and a great result is often 1–2 test steps, i.e. 60–120 seconds of pure will:

• Don't look at the clock or the power. Count pedal strokes, stare at the wall, count to ten on repeat — anything that pulls attention away from "how much longer".
• The first "I can't" is not the end. Almost everyone has another 30–60 seconds behind that thought. A first-ever test is almost always deflated precisely because of early surrender.
• Failure should look like this: cadence drops despite full effort and doesn't come back. Then — and only then — stop pedalling.

Checklist one minute before the start

1. Trainer calibrated, sensors paired, batteries fine.
2. Fans on, window open.
3. Bottle and towel within reach.
4. Phone silenced, household warned.
5. Warm-up done (10 min with 2–3 openers).
6. Mental plan: I hold 90 rpm and I don't negotiate before the first crisis.

After the test comes the best part: a fresh FTP and recalculated zones. What the number means and when not to trust it — see our article on interpreting ramp test results, and if you're still torn between protocols, we compared them in ramp test vs 20-minute FTP test.
