Make this advice more personal

Save your FTP and weight once; every climbing and gearing calculation uses them.

  • Your details stay saved. No need to enter them again, even in other calculators.
  • A narrower range. Your own weight and FTP make it easier to compare calculations.
  • Your next step is ready. Take your details to the climb planner, gearing calculator or nutrition calculator.

The short answer

Plan a climb using distance, average gradient, FTP, weight and bike type. The calculator provides target power and estimated climbing time. Use them as a starting point for pacing.

How we calculate

Climb distance selects a duration category. The model chooses an FTP factor for that category and converts target power into speed and time. Bike type supplies the default bike weight.

What this cannot tell you

An average gradient hides steep sections. Wind, surface, fatigue and an inaccurate FTP reduce the estimate’s reliability. The duration category is a model rule, not a measurement of your capacity.

Common mistakes

  • Using the whole route distance instead of the climb distance.
  • Using an old FTP as if it described your current fitness.
  • Treating target power as a compulsory minimum on a difficult day.

What this tool is for

A practical way to plan harder climbs

A climb is not just a gradient. Duration, effort, body mass, wind, and fueling all shape how the climb feels and how well you can execute it.

Build a pacing plan

Use gradient and duration to choose a more realistic opening effort and avoid overcommitting early.

Keep effort sustainable

A good climb plan protects the rest of the ride or event, not just the first ten minutes of the ascent.

Flag risk early

If the plan depends on aggressive pacing, poor fueling, or unrealistic expectations, the tool should make that obvious.

Common problems riders try to solve

Opening a climb too hard and paying for it later in the ride.

Guessing pacing from power alone without considering gradient or duration.

Underfueling a long climb because the effort was treated like a short effort.

What to check first

Check climb length, average gradient, and whether the effort is steady or variable.

Decide if the goal is finishing cleanly, racing the climb, or protecting the rest of the day.

Make sure fueling and hydration match the expected duration and heat.

What not to change blindly

Do not raise the target effort just because the climb looks short on paper.

Do not ignore longer recovery impact when a climb is one part of a bigger route.

Do not assume the same pacing choice works equally well for every rider profile.

FAQ

FAQ

Is this only useful for racing?

No. It is also useful for long training rides, gran fondos, and route planning when climbs change how the ride should be managed.

Should fueling be part of climb planning?

Yes. On longer climbs or harder days, pacing and fueling work together rather than separately.
