Frequently Asked Questions

How much time does a 10W FTP increase save?

A 10W FTP increase typically saves 1-3 minutes per hour on flat courses and 2-5 minutes per hour on hilly courses. The exact savings depend on your current FTP, the course profile, and conditions like wind. On a 40km flat time trial, expect to save roughly 30-60 seconds per 10W improvement.

Does FTP matter more on flat or hilly courses?

FTP matters on both, but the impact differs. On flat courses, higher FTP lets you overcome aerodynamic drag (speed increases with cube root of power). On hilly courses, FTP improvements have a more linear effect on climbing speed. Generally, you'll see larger percentage time savings on hilly courses.

How much can I realistically improve my FTP?

New cyclists can often improve FTP by 15-25% in their first year of structured training. Intermediate cyclists might see 5-10% annual improvements. Elite cyclists may only gain 1-3% per year. Consistency, proper recovery, and progressive training are key to maximizing gains.

Why use this calculator instead of just testing on the road?

This calculator gives you instant estimates without the need for time-consuming field tests. It helps you set realistic training goals and understand the potential payoff of FTP improvements. For precise predictions on specific courses, use our Cycling Race Pace Calculator with your actual GPX file.
