Sleep and Stress Management to Improve Recovery

If you're not a good sleeper and you've got a marathon coming up, you could be getting away with poor sleep. You only need to recover as hard as your training. Some people that train for marathons and ultra, and they say, I can't get beyond 50 kilometers a week. And then you ask about their nutrition and their stress and their sleep. It's suboptimal. If you want to train hard, you need to recover hard.
