Structured Training Tools for UK Cyclists
Structured training has transformed how UK cyclists prepare for everything from local club time trials to national-level road racing. Whether you train outdoors on the roads of the Chilterns and Peak District or indoors on a smart trainer during the darker winter months, understanding your training zones is the foundation of measurable progress. Our FTP calculator and ramp test calculator help you establish your Functional Threshold Power, while the power zone calculator and heart rate zone calculator translate that into actionable training intensities.
Tracking training load is critical for avoiding overtraining and burnout — a common pitfall for enthusiastic club riders who ramp up volume too quickly in spring. The TSS calculator quantifies the stress of each session, and the training load calculator monitors your acute and chronic load balance over weeks. The recovery calculator then estimates the rest you need between hard efforts, helping you arrive at Saturday's club run or Sunday's sportive feeling fresh rather than fatigued.
For riders looking to benchmark their aerobic fitness, the VO2 max calculator provides an estimate based on your power-to-weight ratio. British Cycling uses similar metrics in their talent identification programmes, and tracking your VO2 max over a training season gives you a clear picture of your cardiovascular development. Combine these tools with a consistent training plan and you will see real, data-driven improvements in your riding.
