FTP is an important metric in cycling as it helps to measure a cyclist's overall fitness level. FTP stands for Functional Threshold Power, which is the highest average power a cyclist can sustain for about an hour when riding. Knowing your FTP allows you to set goals and track progress towards them, so you can maximize performance and become a better cyclist. Aug 4, 2021 marks the start of the Tour de France, the world's most prestigious cycling race. It's a great opportunity to test your FTP and see how you measure up against the world's best cyclists.
