Frequently asked questions

How often should I test my FTP?

Every 4-8 weeks of structured training, or when you feel significantly fitter. FTP can increase 5-20% in a focused training block, so outdated zones mean you're training at the wrong intensity.

Is 200W a good FTP?

Context matters: 200W on a 60kg rider is 3.3 W/kg (solid club level); on a 90kg rider it's 2.2 W/kg (recreational). Watts per kilogram is the better measure of cycling fitness across different body weights.
