How much power does it take to ride 30 km/h?

It depends on position, terrain, wind, tires, and rider size. There is no single number that applies to every rider or route.

Is it faster to lose weight or add watts?

That depends on the terrain and the size of the change. On climbs, weight matters more; on flats, aerodynamics and absolute power usually dominate.

How do wind and gradient interact with speed?

Wind changes the aerodynamic cost, while gradient changes the gravitational cost. Together they can make the same power output look very different on the road.

How do I know if power to speed is the main lever to change?

If a small change produces a clear, repeatable difference in how the ride feels or performs, power to speed is probably a useful lever. If not, move to the next variable rather than making a bigger guess.

When should I get a coach, fitter, or clinician involved?

Get help when the issue keeps returning, when more than one system is involved, or when the symptoms are sharp, persistent, or happening outside normal riding.
