Everything You Need to Know About Running Recovery

The hard run damages you. The recovery adapts you. Skip the second half and you are just accumulating damage. This guide covers what actually drives recovery — and what the wearables genuinely measure.

The four pillars

1. Sleep — non-negotiable. Aim for 7–9 hours, with the last 90 minutes uninterrupted.
2. Nutrition — adequate carbohydrate, 1.6–2.0 g protein per kg body weight, eaten across the day.
3. Stress management — psychological stress and training stress draw from the same cup.
4. Easy days — the easy day IS recovery. Treat it as such.

What HRV actually tells you

Heart-rate variability is the millisecond-level variation between heartbeats. Higher HRV usually means a more parasympathetic, recovered state. But the only useful HRV signal is the trend over 7 to 14 days against your own baseline — single-day numbers are noisy.

Resting heart rate

A 5–10 bpm rise in morning resting HR for two consecutive days is one of the most reliable overtraining signals available — and it costs nothing to measure.

Active recovery vs full rest

Easy Zone 1 spin or walk increases blood flow and can speed perceived recovery. But a true rest day costs nothing and gives the nervous system a real break. Use both.
