Post-Run
Recovery

The first meal after training matters most when the next session is less than eight hours away: that is when replacing carbohydrate and protein early speeds glycogen resynthesis. With a full day in between, the day's total matters more than the “window” of the first minutes.

Ideal ratio: 3:1 (carbohydrates:protein). A banana with 200g Greek yogurt, or rice with egg, are practical and effective options.

Growth hormone (GH) — responsible for protein synthesis and muscle repair — is released primarily during deep sleep. Sleeping 7-9 hours a night is not a luxury for a runner: it's part of training.

Studies with athletes show that increasing sleep to 9-10 hours improves performance, reduces reaction time and decreases injury rates.

Every 3 or 4 weeks of progressive load, schedule a deload week: cut volume substantially — roughly a third — while keeping intensity. That is when the body consolidates its adaptations.

Runners who ignore deload weeks tend to plateau or get injured. Supercompensation — real fitness gains — occurs during recovery, not during load.

The supercompensation principle is the foundation of sports periodization: you apply stress (training), the body breaks down, and during recovery it rebuilds to a slightly higher level than before. Without adequate recovery, only the breakdown happens.

Cardiorespiratory adaptation — higher VO2max, greater capillary density, more mitochondria — happens in the 24-72 hours after the training stimulus. That's the window where sleep, nutrition and rest determine what each workout is actually worth.

Runners who train hard and recover little eventually hit overtraining — when breakdown outpaces adaptation and performance starts to decline. The symptoms are subtle at first: sleep quality worsens, resting HR creeps up, motivation fades.
