What is a good watts per kilo for cycling?

For recreational cyclists, 2-3 W/kg is typical. Club racers are usually 3.5-4.5 W/kg. Professional riders sustain 5-6+ W/kg at threshold.

How do I improve my W/kg?

You can improve W/kg by increasing power through structured training or by reducing body weight, or both. Focus on sustained power improvements through threshold and VO2 max intervals.

Is W/kg more important than absolute power?

On flat terrain, absolute power matters more. On climbs, W/kg is the key metric since you are lifting your own weight against gravity.

What power should I use for this calculation?

Use your FTP (Functional Threshold Power) for the most meaningful comparison. This is the power you can sustain for about one hour.

Power-to-Weight Formula

W/kg = Power Output (watts) / Body Weight (kg)

This ratio is the single most important metric for climbing performance in cycling. Professional Grand Tour climbers typically sustain 6+ W/kg at threshold.
