What Is a Good Watts Per Kilogram (W/kg)?
A good power-to-weight ratio depends on your goals — but here is what each level unlocks. Enter your numbers to see where you stand.
Power-to-weight
3.33W/kg
Advanced (3.2–4.0 W/kg) — Dedicated amateur, competitive on hard group rides and local events.
The short answer
For amateur men, a rough guide is: under 2 W/kg is beginner, 2.5–3.2 is a solid intermediate level, 3.2–4.0 is advanced, and 4.0+is competitive. Women's bands run a little lower for the same level. Most riders sit between two of these, not neatly inside one.
Power-to-weight is simply your FTP divided by your body weight, and it is the figure cyclists reach for whenever the question involves moving your own mass — climbing above all.
The formula
W/kg = FTP (watts) ÷ body weight (kg)
Don't know yours? The W/kg calculator works it out from your FTP and weight, and the W/kg chart shows the full set of rider categories.
What good watts per kilogram looks like, by level
Power-to-weight by rider level for amateur men. These are evergreen orientation ranges — most riders sit between two of them, and women’s bands run a little lower for the same level.
| Category | W/kg |
|---|---|
| Beginner | Under 2.0 |
| Recreational | 2.0–2.5 |
| Intermediate | 2.5–3.2 |
| Advanced | 3.2–4.0 |
| Competitive | 4.0–5.0 |
| Elite | 5.0+ |
What watts per kilogram you actually need, by goal
A better way to pick a target: start from what you want to do on the bike. Illustrative ranges, not hard cutoffs.
| Goal | Typical W/kg |
|---|---|
| Casual fitness | 2.0–2.5 W/kg |
| Fast group rides | 2.5–3.2 W/kg |
| Competitive group rides | 3.2–4.0 W/kg |
| Local racing | 4.0–5.0 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. Aim about one band above where you are now rather than at a leaderboard number.
Why watts per kilogram, not just FTP
Two riders with an identical 250 W FTP can be a full category apart. At 70 kg that is 3.6 W/kg (advanced); at 95 kg it is 2.6 W/kg (recreational). 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 — not raw watts — is the fair comparison between riders of different sizes.
It also means there are two honest ways to raise the ratio:
- 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 — but it should be gradual, because aggressive dieting saps power and wrecks recovery.
For most amateurs the sustainable path is to build fitness first and let body composition settle alongside consistent training. A good W/kg that comes from being fitter lasts; one chased through under-fuelling rarely does.
What counts as good changes with age
Power-to-weight tends to peak in the 20s and 30s and ease down from there, so a “good” W/kg for a masters rider is rightly judged against peers of a similar age. See W/kg by age for typical ranges across the decades — and remember the most useful benchmark is always your own trend.
Frequently asked questions
- What is a good W/kg for cycling?
- As a rough guide for amateur men, under 2 W/kg is beginner, 2.5–3.2 is a solid intermediate level, 3.2–4.0 is advanced, and 4.0+ is competitive. Women’s bands run a little lower for the same level. The honest answer is that "good" depends on your goals — a strong W/kg for enjoying fast group rides is well below what local racing demands.
- Is 3 W/kg good?
- Yes. Around 3 W/kg is a solid intermediate power-to-weight ratio that lets you ride strongly on most fast group rides. It is reached through consistent training and is a realistic medium-term goal for many committed recreational riders.
- Is 4 W/kg good?
- Four W/kg is a genuinely strong, advanced-to-competitive figure, often cited as a rough threshold for being competitive in amateur road racing. Most riders need years of consistent, structured training to reach it.
- What is a good W/kg for a beginner?
- New riders commonly sit below 2 W/kg, and many start around 1.5–2.0. That is a completely normal starting point, and it is also where power-to-weight climbs fastest — consistent training can add 0.5–1.0 W/kg over a first season as your FTP rises.
- What W/kg should I aim for?
- Pick a target from your goal, not a leaderboard. Roughly: 2.0–2.5 W/kg for comfortable fitness riding, 2.5–3.2 to hang on in fast group rides, 3.2–4.0 to make the selections on hard rides, and 4.0+ for local racing. Aim one band above where you are now, and let your own trend — not anyone else’s number — be the measure.
