Mastering Your FTP: 20-Minute vs. Ramp Testing for Competitive Cyclists

Understanding Functional Threshold Power

As a coach, I often see athletes obsessing over their Functional Threshold Power (FTP). It is the gold standard for measuring cycling performance, representing the maximum power you can sustain for an hour. Knowing this number is essential for structuring your training zones effectively.

Testing can be daunting, but it is the most reliable way to gauge your fitness. Whether you are training for a crit or a long-distance sportive, your FTP dictates the intensity of your intervals and ensures you are not burning out during your sessions.

The 20-Minute Test

The traditional 20-minute test is a test of mental fortitude. After a thorough warm-up, you ride as hard as you possibly can for twenty minutes. You then take 95% of the average power output from that duration to estimate your hour-long threshold.

This test requires excellent pacing. If you start too hard, you will fade in the final minutes, skewing your results. It is a true test of your ability to suffer and maintain a steady rhythm under extreme physical fatigue.

The Ramp Test

The ramp test is a more modern approach. You start at a low intensity and increase your wattage incrementally every minute until you reach total exhaustion. It is shorter, less mentally taxing, and provides a clear picture of your VO2 max ceiling.

Many athletes prefer the ramp test because it does not require the same level of tactical pacing. You simply push until you physically cannot turn the pedals anymore. It is highly effective for those who struggle with the psychological weight of the 20-minute effort.

Will It Make me Faster

Testing itself does not make you faster; it is the data that follows that changes the game. By establishing an accurate baseline, you can set your training zones to ensure you are working in the right physiological energy systems to drive adaptation.

When your zones are too low, you are not providing enough stimulus for change. When they are too high, you risk overtraining. Regular testing allows you to adjust your training load as your body gets stronger, ensuring you continue to push your boundaries.

How long before I see improvements

Adaptation takes time. In my experience, most cyclists see a measurable increase in power after six to eight weeks of consistent, structured training. Patience is your greatest ally when chasing higher numbers on the power meter.

Avoid the temptation to test every week. Frequent testing interrupts your training cycle and prevents the body from recovering fully. Stick to a structured plan and re-test once every two months to track your trajectory towards your goals.

To raise your FTP, you must incorporate interval training that targets your threshold. Sweet spot training, VO2 max intervals, and sustained tempo rides are all vital components of a balanced programme that will help you break through plateaus.

Remember to prioritise your recovery. Improvements in power are made during the rest periods between your hard sessions, not during the sessions themselves. Keep your sleep and nutrition on point to maximise your gains.

10 alternative training techniques

1. Sweet Spot Intervals: These involve riding at 88-94% of your FTP. This intensity is the 'sweet spot' because it provides a high training stimulus while allowing for enough recovery to perform again the next day. It is excellent for building aerobic capacity and muscular endurance without excessive systemic fatigue.
2. VO2 Max Blocks: Short bursts of high-intensity efforts at 110-120% of your FTP. These sessions force your heart and lungs to work at maximum capacity, significantly increasing your oxygen utilisation efficiency. They are incredibly taxing but essential for increasing your top-end power and anaerobic ceiling for racing.
3. Tempo Rides: Sustained efforts at 75-85% of your FTP. These rides teach your body to become efficient at burning fat as a fuel source while sparing glycogen. They are fundamental for building the base fitness required for long-distance events and improving your ability to ride hard for hours.
4. Over-Under Intervals: You alternate between segments slightly above and slightly below your FTP. This method trains your body to recover while still working at a high intensity, which is crucial for handling surges in a race environment or climbing steep gradients while maintaining a high average speed.
5. Cadence Drills: Practising high and low cadence work improves your pedalling efficiency. By training at different revolutions per minute, you recruit different muscle fibres and improve your neuromuscular coordination. This makes you a more versatile rider capable of adapting to varying terrain and changing wind conditions on the road.
6. Strength Training: Off-the-bike work targeting your glutes, hamstrings, and core. A stronger posterior chain allows for more power transfer to the pedals. By improving your foundation, you reduce the risk of injury and ensure that your muscles can support the high loads required during intense cycling efforts.
7. Isometric Holds: Holding a position under tension helps build stability. For cyclists, this means focusing on core engagement while in an aerodynamic position. Improving your stability allows for better power output because less energy is wasted on swaying or shifting weight, keeping your centre of gravity perfectly balanced.
8. Threshold Pyramids: Structuring intervals that increase in length then decrease. This builds psychological resilience as you manage the difficulty of the longer middle efforts. Pyramids are a fantastic way to challenge your pacing strategy while ensuring you get a high volume of quality work at your threshold.
9. Active Recovery Rides: Low intensity, high-cadence spinning. These are not just rest days; they are active sessions designed to increase blood flow to the muscles, flushing out metabolic waste products from previous hard sessions. This accelerates your recovery and prepares you for the next block of high-intensity training.
10. Descending Practice: Technical skill work that saves energy. Being comfortable at high speeds on descents means you can maintain momentum without braking unnecessarily. By mastering your bike handling, you gain free speed and reduce the physical output required to stay with the pack, giving you an advantage.
