Injury-aware running
Practical advice on avoiding overtraining.
Overtraining sneaks up. Watch sleep quality, mood, motivation and resting heart rate as much as training metrics.
Easy days easy
Most overtraining comes from too-fast easy days, not too-fast intervals.
One quality session a week
Two is fine if you're recovered. Three is rarely useful for amateurs.
Sleep is training
Adaptation needs recovery time. Sleep is the cheapest performance gain.
