FTP Testing: Ramp Test vs 20-Minute Test vs 60-Minute — Which Is Right?

Your FTP (Functional Threshold Power) is the most important number in structured training. Get it wrong and every workout becomes the wrong intensity. There are three main testing methods, and they all have trade-offs.

Method 1: Ramp Test

How it works: Power increases in steps (typically 20W per minute) until failure. Your FTP is estimated as 75% of your best 1-minute power during the test.

Pros: Takes ~20 minutes. Low mental demand — just ride until you physically can't. Consistent results if you test regularly.

Cons: Overestimates FTP for anaerobic athletes (sprinters, track riders). Underestimates for pure diesel engines. It's an estimate, not a measurement.

Best for: Most riders. Fast, repeatable, and good enough for setting training zones.

Method 2: 20-Minute Test

How it works: Ride as hard as you can for 20 minutes. Multiply average power by 0.95 to estimate 60-minute power.

Pros: More accurate than ramp test for most riders. Rewards pacing skill.

Cons: Pacing is crucial — go too hard early and you blow up, go too easy and you under-test. Requires experience to get right.

Best for: Riders who can pace well and want a more accurate number than a ramp test.

Method 3: 60-Minute Test (Gold Standard)

How it works: Ride as hard as you can for a full hour. Your average power is your FTP.

Pros: By definition, this is FTP. No estimates, no multipliers.

Cons: Brutally hard. Requires perfect pacing. Mentally exhausting. Most amateurs won't push hard enough for a true max effort.

Best for: Serious racers and data nerds. Not recommended for beginners.

Which Should You Use?

  • New to structured training → Ramp test. Fast, consistent, low mental load.
  • Experienced, want accuracy → 20-minute test. Learn pacing, get a reliable number.
  • Racing, need precision → 60-minute test, once per season. Use ramp tests in between to track changes.

Whatever method you choose, test consistently. Same protocol, same conditions, same time of day. The trend matters more than any single number.
