FTP by Age
How cycling FTP tends to change across the decades — and how much of that decline consistent training can quietly cancel out.

An FTP of 250 W (225–265 W) — Consistently trained and comfortably strong on fast group rides, including on rolling terrain.
These are absolute-power bands. Because rider weight matters too, your watts per kilogram tells the rest of the story — see below.
Short answer
As a training reference for male amateurs who ride consistently, at the 75 kg reference weight, FTP sits around 240–330 W in the 20s, 220–325 in the 40s, 205–305 in the 50s, and 180–280 in the 60s. Full chart below.
Read these as orientation, not as a standard you should be meeting. The underlying decline is about 0.5–1% a year from the late 30s — a few watts a year on a 250 W FTP, and easily swamped by the gains available from training more consistently. Many amateurs record their highest ever FTP in their 40s.
Cycling FTP by age chart
Illustrative age-adjusted FTP references by decade at the 75 kg reference weight, for male amateurs who keep training, alongside the share of the 20s reference band each decade is modelled to hold.
| Age | Reference FTP | Share of reference |
|---|---|---|
| Under 20 | Developing | Still rising |
| 20–29 | 240–330 W | ~100% |
| 30–39 | 235–330 W | ~97–100% |
| 40–49 | 220–325 W | ~92–98% |
| 50–59 | 205–305 W | ~85–93% |
| 60–69 | 180–280 W | ~75–85% |
| 70+ | 155–250 W | ~65–75% |
What these numbers are: One model drives this table and the W/kg by age table, projected into watts at 75 kg, so the two cannot disagree — the “share of reference” column is that model. These are illustrative age-adjusted training references, not population averages or percentiles — we are not aware of a public dataset of amateur cyclist FTPs by age that would support those. They take a trained-amateur reference range and scale it by an approximate age-related decline in aerobic capacity, which is an approximation rather than evidence that threshold power itself falls at the same rate: FTP is a trainable fraction of aerobic capacity, so training history, body composition, and current fitness move an individual's numbers far more than age does. The numeric ranges here are referenced to trained male recreational and amateur cyclists — the population the underlying coaching convention was built around. Female cyclists should not read them as a percentile or reference table: the physiology differs, and we do not publish separate numeric ranges for women because we do not yet have a source we consider solid enough to stand behind. Full methodology and sources.

How FTP changes with age
The underlying physiology is well established. Maximal aerobic capacity — the engine your FTP draws on — tends to peak somewhere in the 20s to mid-30s, then declines gradually at roughly 0.5–1% per year from the late 30s, with the rate picking up after about 60. Maximum heart rate drifts down, and the body recovers a little more slowly each decade.
That sounds discouraging until you notice how small it is year-to-year. A 1% annual drift is a few watts on a 250 W FTP — easily swamped by the gains available from simply training more consistently. Which is exactly why so many amateurs record their highest ever FTP in their 40s: they were fitter, not younger.
Worth being precise about one thing, since the table above is built by scaling a reference with that curve: FTP is not the same measurement as VO₂ max. Threshold power is a fraction of your aerobic ceiling, and that fraction responds to training in its own right. Using the aerobic-capacity curve gives us a defensible shape for an age-adjusted reference; it is not a claim that your FTP falls at precisely that rate.
Training beats the age curve
The decline numbers describe what happens on average, including to people who stop training. Riders who keep at it tell a very different story:
- Consistency offsets most of it. The largest part of age-related loss in the data comes from doing less, not from age itself. Keep riding and the curve flattens dramatically.
- Newcomers improve at any age. Start structured training at 55 and you’ll make the same big early gains a younger beginner would — the body still adapts.
- Recovery becomes the lever. Older riders adapt fine but recover slower, so the riders who thrive are the ones who manage fatigue and don’t bury themselves chasing every session. Sustainable, adaptive training matters more with each decade.
Why power-to-weight matters even more with age
Because FTP in watts depends on body size, age comparisons are cleaner in watts per kilogram. If body weight drifts up over the years, W/kg can fall even when your FTP holds steady — so power-to-weight is often the more honest gauge of how you’re ageing as a rider. See W/kg by age for that breakdown, work out your own ratio with the W/kg calculator, and check what counts as a good FTP for the full context behind the numbers.
Frequently asked questions
- At what age does FTP peak?
- For most riders, the physiological ceiling for sustainable power falls somewhere in the 20s to mid-30s, when trainability and recovery are at their best. In practice, though, many amateurs post their highest FTP in their late 30s or 40s simply because that is when they finally train consistently — training history often outweighs the underlying age curve.
- How much does FTP decline with age?
- Aerobic capacity tends to fall by roughly 0.5–1% per year from the late 30s onward, accelerating after about 60. FTP does not necessarily track that exactly, though — threshold power is a trainable fraction of aerobic capacity, so it can rise even as the underlying ceiling drifts down. Riders who keep training lose far less than the curve implies, and a fit 55-year-old routinely out-powers a sedentary 30-year-old.
- Can older cyclists still improve their FTP?
- Absolutely. Anyone new to structured training — at any age — can make large early gains, and masters riders frequently raise their FTP for years. Age lowers the ceiling slowly; it does not stop progress. Recovery simply needs more respect, which makes adaptive, well-paced training especially valuable later on.
- What is a good FTP for a 50-year-old?
- It depends heavily on weight and training history. As an illustrative reference for male amateurs in their 50s who train consistently, around 205–305 W at 75 kg — a coaching orientation range rather than a measured average, so treat it accordingly. The fairer measure is power-to-weight: compare your W/kg against riders of a similar age rather than chasing a younger rider’s watts.
- What is the average FTP for a 40-year-old cyclist?
- We do not have a reliable answer, and we would rather say so than publish a number. We are not aware of a public dataset of amateur cyclist FTPs by age, and figures drawn from training-app users are biased upward because those riders already train. What this page gives you instead is a coaching reference for consistently training male amateurs — useful for orientation, but not an average of all 40-year-olds.
- Is FTP by age the best way to judge my fitness?
- It is useful context, but your own trend is better. These are illustrative coaching references rather than population percentiles, they are drawn from male amateur riders, and they depend heavily on weight and training history. The number you actually control is whether your FTP — and your power-to-weight — is holding or climbing year over year.
