When Things Don’t Feel Good Outside the Data

Numbers can confirm capacity. They can’t always reflect state.

You can be hitting pace, holding volume, and ticking every box, while still feeling off in your body. Tight without injury. Heavy without soreness. Flat without a clear reason.

That doesn’t mean the data is wrong. And it doesn’t mean your experience is unreliable.

It means adaptation is happening in layers the watch can’t see: nervous system load, hormonal fluctuation, emotional stress, or the simple accumulation of effort over time.

In endurance training, learning to respect how you feel alongside what the data says is a skill, not a weakness.
