A plateau in cycling is a period where your performance, fitness, or key metrics stop improving despite continuing to train consistently.
It often shows up as stable power at threshold, no gains in endurance pace, unchanged heart rate response, or repeated workouts feeling equally hard with similar results.
Common causes include too much training at the same intensity, not enough recovery, insufficient progressive overload, fueling gaps, stress, poor sleep, or repeating similar routes and sessions.
To break a plateau, adjust one main lever at a time, such as adding a structured training plan, changing workout focus, increasing recovery quality, or improving carbohydrate intake around harder rides.
If the plateau lasts more than 3 to 6 weeks, it can help to review training load trends, fatigue signals, and whether your goals match your current training block.
