Raise your functional threshold calmly over winter with a steady, progressive build that prioritises control, repeatability, and smart recovery—so fitness climbs without burnout. Designed for riders with a solid base, this plan focuses on sustainable work that nudges FTP up while keeping legs fresh enough to show up again tomorrow. At checkout, pick your metric (Power or RPE) and all targets are delivered in that format, with clear guidance to keep effort honest and durable through colder months. Most athletes choose LIFETIME (Live Updates) for ongoing refinements and cues; NOW (Static) is available if you just want today’s fixed edition.
