There is no single population-wide “average FTP” that tells you whether your cycling power is good. Watts per kilogram (W/kg) is a better starting point for comparing riders of different sizes, while absolute watts matter more on flatter courses. As a practical reference, Garmin’s current FTP classifications label 2.79–3.92 W/kg as “Good” for men and 2.36–3.32 W/kg as “Good” for women. Those bands are useful context—not a verdict on your fitness or race potential.
FTP is a performance estimate, not a perfectly defined physiological threshold. Different test protocols can give different answers for the same athlete, and research shows that the common “95% of a 20-minute test” shortcut does not reproduce maximal lactate steady state equally well for everyone.
Good FTP benchmarks at a glance
Garmin publishes the following W/kg classifications based on the Allen/Coggan power-profile framework. They are among the clearest public reference bands, but they should be treated as performance categories, not population averages.
| Rating | Men | Women |
|---|---|---|
| Superior | 5.05+ W/kg | 4.30+ W/kg |
| Excellent | 3.93–5.04 W/kg | 3.33–4.29 W/kg |
| Good | 2.79–3.92 W/kg | 2.36–3.32 W/kg |
| Fair | 2.23–2.78 W/kg | 1.90–2.35 W/kg |
| Untrained | <2.23 W/kg | <1.90 W/kg |
A useful benchmark is one you can repeat. Your FTP trend measured with the same power meter, test method and conditions is usually more useful for training than comparing one number with strangers online.
What FTP actually measures
Functional Threshold Power was developed as a practical way to anchor cycling training around a rider’s sustainable high-intensity power. In everyday training language, FTP is often described as roughly the power you could sustain for around an hour. In practice, however, most riders do not perform a maximal 60-minute test. They use a 20-minute test, ramp test, longer time trial or an estimate generated from recent ride data.
FTP is useful
It gives you one repeatable number for setting power zones, tracking changes and comparing training blocks. Garmin, cycling computers and training platforms can all build zones from FTP.
FTP is not a laboratory law
Studies comparing FTP with lactate-based thresholds have found meaningful individual differences. Two athletes with the same FTP can also have very different durability above and below threshold.
One study of trained cyclists found that a 20-minute time trial was highly repeatable, but the conventional 95% conversion still overestimated maximal lactate steady-state power by an average of about 12 W. Another study found large limits of agreement between FTP and common lactate thresholds. That is why an FTP of 280 W should be read as “a useful training estimate around 280 W,” not as an exact biological boundary.
Is 200, 250 or 300 watts a good FTP?
Absolute power sounds intuitive, but body mass changes the interpretation. The table below shows the same FTP at four different body masses.
| FTP | 55 kg | 65 kg | 75 kg | 85 kg |
|---|---|---|---|---|
| 200 W | 3.64 W/kg | 3.08 W/kg | 2.67 W/kg | 2.35 W/kg |
| 250 W | 4.55 W/kg | 3.85 W/kg | 3.33 W/kg | 2.94 W/kg |
| 300 W | 5.45 W/kg | 4.62 W/kg | 4.00 W/kg | 3.53 W/kg |
200 W FTP
At 65 kg, 200 W is 3.08 W/kg; at 85 kg it is 2.35 W/kg. The same wattage can therefore represent very different relative fitness.
250 W FTP
At 75 kg, 250 W equals 3.33 W/kg. That sits comfortably inside Garmin’s “Good” male range and at the upper edge of its “Good” female range.
300 W FTP
At 75 kg, 300 W is exactly 4.00 W/kg. At 85 kg it is 3.53 W/kg. Both can be strong results, but they imply different climbing performance.
Absolute watts vs W/kg vs aerodynamics
W/kg becomes increasingly important when gravity dominates: long climbs, repeated accelerations uphill and courses with substantial elevation. On flat roads, absolute sustainable power and aerodynamic drag become more important. That distinction matters especially in triathlon.
Watts per kilogram matters most when...
- the road climbs for long periods
- speed is relatively low and gravity is a large resistance
- you are comparing climbing ability between riders
Absolute watts and aero matter most when...
- the course is flat or rolling
- you can hold an aerodynamic position for long periods
- race speed is high enough for aerodynamic drag to dominate
A lighter rider with 4.0 W/kg is not automatically faster on a flat Ironman bike leg than a heavier rider at 3.5 W/kg. If the heavier rider produces more absolute watts and has a lower effective drag area, the result can reverse. That is why triathletes should not optimize W/kg at the expense of sustainable power, fueling or aerodynamics.
Our road bike vs triathlon bike analysis shows how rider position can change speed even when power stays the same.
What is a good FTP for triathlon?
For triathlon, FTP is best used as a ceiling and training anchor, not as a race score by itself. A good triathlon cyclist needs to produce a high fraction of sustainable power while preserving the ability to run.
Short-course triathlon
Sprint and Olympic racing place a greater premium on high sustainable power because the bike is shorter and the run begins with less accumulated fatigue.
70.3 and Ironman
Long-course performance depends increasingly on durability, aerodynamics, nutrition and pacing. An impressive FTP can be wasted if the athlete rides too hard early or cannot hold aero position late in the race.
For long-course triathlon, record the power you can actually sustain in race position during long rides, how much heart rate drifts, how well you fuel and how you run afterward. Those data tell you more about race readiness than FTP alone.
Why different FTP tests give different numbers
| Method | What it does well | Main limitation |
|---|---|---|
| 20-minute test | Simple, repeatable and widely used | The 95% conversion is not equally accurate for every rider |
| Ramp test | Short and easier to pace | Result depends strongly on how your short-duration power relates to sustained power |
| Long time trial | More directly tests sustained output | Harder mentally and physically; pacing matters |
| Automatic estimate | Convenient and can use normal riding data | Depends on the algorithm and whether your recent rides contained enough hard efforts |
The practical rule is simple: do not compare FTP changes from different protocols as if they were identical measurements. If your goal is to track progress, repeat the same method on the same power source under similar conditions.
How to improve FTP without chasing the number
-
Build enough easy aerobic volume
Low-intensity riding supports the aerobic base that lets you absorb harder training and accumulate quality work over time.
-
Train around threshold
Structured intervals near your sustainable high-intensity range improve the ability to produce power for long periods. Progress duration before turning every session into a maximal test.
-
Use VO2-max work selectively
Intervals above FTP can raise aerobic capacity and create room for threshold power to improve, but the sessions are demanding and need recovery.
-
Retest consistently
Use the same protocol and power meter. A smaller change measured consistently is more meaningful than a bigger change created by switching test methods.
Frequently asked questions
What is a good FTP in watts per kilogram?
Garmin’s current reference table classifies 2.79–3.92 W/kg as “Good” for men and 2.36–3.32 W/kg as “Good” for women. Treat those as broad performance categories rather than population averages.
Is 3 W/kg a good FTP?
Three W/kg is a solid recreational benchmark and falls within Garmin’s “Good” category for men and women. Your course, aerodynamics and durability still determine how that power translates into speed.
Is a 250 W FTP good?
It depends on body mass. At 65 kg, 250 W is 3.85 W/kg; at 85 kg it is 2.94 W/kg. Both are 250 W, but the relative performance is different.
Is a 300 W FTP good?
For most recreational cyclists, 300 W is a strong absolute FTP. At 75 kg it equals 4.0 W/kg; at 85 kg it equals 3.53 W/kg.
Does FTP equal one-hour power?
Not exactly. FTP is commonly described in relation to roughly hour-long sustainable power, but modern tests estimate it in different ways. The number should be treated as a practical training metric rather than a guaranteed 60-minute performance.
Is 95% of 20-minute power always accurate?
No. Research in trained cyclists has found meaningful individual bias when 95% of a 20-minute test is used to predict maximal lactate steady state.
Should triathletes care more about FTP or W/kg?
Both matter, but flat long-course triathlon also rewards absolute sustainable power and low aerodynamic drag. On hilly courses W/kg becomes more important.
