The Runner's Recovery Library

Runners need more sleep than sedentary adults — 8 to 10 hours during heavy training. Here's the science, the targets by training load, and how to get there.

Sleep drives running performance more than any other recovery input. Here's what the evidence shows about sleep, VO2max, pace, and race-day output.

From one bad night to chronic restriction — here's exactly how sleep deprivation degrades training adaptations, immunity, and injury risk.

Strategic napping can buy back lost sleep and lift afternoon training quality — but only if you do it right. The runner's nap playbook.

Recovery days aren't rest days. Here's exactly what to do — and what to skip — to actually absorb your training.

Easy spin or walk? Pool? Yoga? Here's what the evidence supports for active recovery, and what's marketing.

Foam rolling can ease tightness and improve range of motion — but it's overhyped. Here's what to roll, how often, and the mistakes to avoid.

Cold plunges and ice baths can speed recovery — but they can also blunt training adaptations. Here's when to use them and when to skip.

Most runners don't need more flexibility — they need usable mobility through the ranges that running demands. Here's the targeted program.

The 24 hours after a long run determines how the next training block goes. Here's the protocol — fuel, sleep, movement, and what to skip.

By the time most runners notice overtraining, it's been building for weeks. Here are the early signs to catch — before it costs a season.

Burnout is the psychological side of overtraining. Here's how to spot it early — and how to come back without quitting the sport.

Recovery debt is the accumulated cost of under-recovering across a training block. Here's how it builds — and how to pay it down before it forces you to stop.

Mental fatigue degrades endurance performance as much as physical fatigue — and most runners never account for it. Here's what to do.
