What Is a Good W/kg for Cycling?
Straight answers for the numbers riders actually ask about — 2.5, 3, 4, and 5 W/kg — in terms of what each one gets you on the road.
Power-to-weight
3.33W/kg
Experienced (3.0–3.5 W/kg) — Consistently trained and comfortably strong on fast group rides, including on rolling terrain.
Short answer
As a coaching reference for trained male amateurs: 3 W/kg is solid trained fitness and a realistic target for most committed recreational riders. 4 W/kg is very good — the conventional threshold for being competitive in amateur racing. 2.5 W/kg is decent recreational fitness, and 5 W/kg is exceptional, at the edge of elite.
The more useful answer: aim one band above where you are now. A 0.5 W/kg step changes what you can do on the road and is reachable in a realistic timeframe — unlike a number borrowed from someone else's season.
Is 2.5, 3, 4, or 5 W/kg good?
Six numbers, six honest verdicts — what each actually means for the riding you do.
2.0 W/kg
A normal, honest starting point
Where most people land when they first test with structure. It is enough to enjoy flat and rolling rides and to finish a social group ride, though you will drift off the back on climbs. It is also the level that improves fastest — six months of consistent riding moves this number more than any other.
How to reach 2.5 W/kg →2.5 W/kg
Genuinely decent recreational fitness
You can hold a club ride on flat terrain and ride for two or three hours without falling apart. Hills are still where you lose contact. Most riders who train two or three times a week without much structure end up somewhere around here, and it is nothing to apologize for.
How to reach 3.0 W/kg →3.0 W/kg
Yes — this is solid, trained fitness
The number most amateurs are really asking about, and the answer is yes. At 3 W/kg you sit in the group on most club rides including moderate climbs, take turns on the front, and finish sportives comfortably. It reliably takes consistent training to get here, which is exactly why it counts.
How to reach 3.5 W/kg →3.5 W/kg
Strong. You are the fit one in most groups
You climb well for your size, you are rarely the limiter on a fast group ride, and you can start thinking about racing. Reaching this from 3.0 usually takes a year or more of structured training — the easy gains are behind you and the work becomes deliberate.
How to reach 4.0 W/kg →4.0 W/kg
Very good — the conventional racing threshold
This is the figure most often cited as the gateway to being competitive rather than just present in amateur road racing. Outside racing it makes you one of the strongest riders in almost any club. Most riders who get here have trained consistently for several years.
How to reach 4.5 W/kg →5.0 W/kg
Exceptional — the edge of elite
Domestic-elite and professional territory, and out of reach for the large majority of amateurs no matter how well they train. Genetics and training history both have to cooperate. If this is your target, be honest that it is a multi-year project with no guarantee.
What reaching 5.0 W/kg takes →What these numbers are: These verdicts are coaching judgments about what each level unlocks on the road, not population statistics, and age shifts them too. 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.
What W/kg you actually need, by goal
A better way to pick a target: start from what you want to do on the bike rather than from a category label.
| Goal | Reference W/kg |
|---|---|
| Casual fitness riding | 2.0–2.5 W/kg |
| Keeping up on club rides | 2.5–3.0 W/kg |
| Riding strongly in fast groups | 3.0–3.5 W/kg |
| Making the selections | 3.5–4.0 W/kg |
| Local and regional racing | 4.0–4.5 W/kg |
| Front of the amateur field | 4.5–5.0 W/kg |
| Elite racing | 5.0+ W/kg |
The honest takeaway: a good W/kg is the one that lets you do what you enjoy. If your goal is finishing a hilly sportive feeling strong, 3.2 W/kg is a complete success and 4.5 would be irrelevant effort. Want the full scale and the FTP each level takes at your body weight? That is on the W/kg chart.
Three things that change what “good” means
Before you judge your own number against any of the above, three caveats do real work:
- Your sex. The conventional bands — ours included — are referenced to trained male amateurs. The physiology differs enough that they are not a female reference table, and we do not publish numeric ranges for women because we do not have a source robust enough to justify them. If you are a woman, compare against riders of the same sex rather than reading these labels as your own.
- Your age. Power-to-weight tends to peak in the 20s and mid-30s and ease down after that, so a good W/kg for a masters rider is rightly judged against peers of a similar age. See W/kg by age for the ranges across the decades.
- How you tested. A ramp-test FTP and a 20-minute-test FTP are not interchangeable, and the gap between them can exceed a year of genuine training. A W/kg is only as comparable as the FTP underneath it — see ramp test vs 20-minute test.
Why W/kg and not just FTP
Two riders with an identical 250 W FTP can be two bands apart. At 70 kg that is 3.6 W/kg (advanced); at 95 kg it is 2.6 W/kg (intermediate). On any climb the lighter rider simply rides away, because what you fight going uphill is power relative to weight. That is why power-to-weight is the fair comparison between riders of different sizes — though on the flat, raw watts still rule, which is why what counts as a good FTP is worth knowing too. For when each number actually decides the outcome, see FTP vs W/kg.
So what should you actually target?
One band up. That is the entire recommendation, and it holds at every level:
- Raise FTP — the durable lever. Consistent endurance volume plus well-timed Zone 2 work and threshold efforts build power you keep. Map your FTP to your training zones so the work lands where it counts.
- Lose excess weight, carefully. For some riders there is healthy weight to shed, which lifts the ratio without touching power. It should be gradual: aggressive dieting saps power and wrecks recovery, so a W/kg gained that way rarely lasts.

Frequently asked questions
- Is 2.5 W/kg good?
- It is decent recreational fitness. At 2.5 W/kg you can hold a club ride on flat terrain and ride comfortably for two to three hours, though climbs are where you lose contact. Most riders training a few times a week without much structure land around here — it is a solid base, and the next 0.5 W/kg is very achievable.
- Is 3 W/kg good?
- Yes. Three W/kg is solid, genuinely trained fitness: you sit in the group on most club rides including moderate climbs, contribute to the rotation, and finish sportives comfortably. It takes consistent training to reach, and it is a realistic medium-term goal for most committed recreational riders.
- Is 4 W/kg good?
- Four W/kg is very good — the figure most commonly cited as the threshold for being competitive rather than merely present in amateur road racing. Outside racing it makes you one of the strongest riders in almost any club. Most riders need several years of consistent, structured training to get there.
- Is 5 W/kg good?
- Five W/kg is exceptional and sits at the entry to elite-level power-to-weight. It is beyond the large majority of amateurs regardless of how well they train, because genetics and training history both have to cooperate. Treat it as a multi-year project rather than a target, if at all.
- What W/kg should an amateur cyclist aim for?
- Aim one band above where you are now, not at a leaderboard. If you are at 2.4, target 2.5–3.0; if you are at 3.1, target 3.5. A 0.5 W/kg step is large enough to change what you can do on the road and small enough to reach in a realistic timeframe. Chasing a distant number is how riders end up frustrated at a level they should be proud of.
- What is a good W/kg for a woman?
- Honestly: not one we can give you in numbers. The bands quoted on most cycling sites, ours included, are referenced to trained male amateurs, because that is the population the underlying convention was built around. Sex-based physiological differences mean they do not transfer directly, and we do not publish a separate numeric table for women because we do not have a source we consider solid enough to stand behind — inventing an offset would be worse than saying nothing. Comparing against riders of the same sex, similar age, and similar training history is far more informative than any generic chart, and your own trend over time is better still.
- What is a good W/kg for a beginner?
- New riders commonly sit below 2 W/kg, and many start between 1.5 and 2.0. That is a completely normal starting point, and it is also where power-to-weight climbs fastest — consistent training can add 0.5 to 1.0 W/kg over a first season as your FTP rises.
