Sweetspot training involves extended intervals, riding for 3x15 minutes at an effort equivalent to 85-95% of an athlete’s functional threshold power (FTP). 5 minute recovery periods between sets provide just enough rest to go again. These sessions are physically and mentally fatiguing. They require appropriate fueling before, during and after, as well as mental focus throughout to achieve the full sets. The closer the athlete is working to their FTP, the tougher the session. Sweetspot training is a highly effective method for attaining physiological adaptations and building stamina.
