Most runners focus on mileage, splits, and fueling—but there’s one key performance enhancer that’s often overlooked: sleep. Elite athletes and sports scientists increasingly agree that rest isn’t just recovery—it’s training.

Sleep and Performance: What Science Says

During deep sleep, the body releases human growth hormone (HGH), which repairs muscles, rebuilds tissues, and restores energy. Your immune system strengthens, the brain consolidates motor memory (important for running form), and muscles rebuild stronger.

Sleep deprivation can lead to:

• Slower reaction times and decision-making

• Increased injury risk

• Poor glycogen storage

• Reduced endurance and mental focus

Simply put: if you’re not sleeping well, your training gains are compromised

What Elite Runners Are Doing

Top runners are making sleep a priority—right alongside workouts and recovery days.

• Eliud Kipchoge sleeps 9+ hours per night and takes a daily nap to support his high-volume training.

• Molly Seidel calls sleep her “number one recovery tool.”

• Jakob Ingebrigtsen is known for dialing back screen time and evening stress to protect sleep quality.

Coaches across the globe now structure training schedules to ensure athletes can rest, especially before and after intense sessions.

Sleep Tech: Measuring What Matters

Devices like the Whoop Strap, Oura Ring, and Garmin sleep trackers are giving runners new insight into recovery. These tools track heart rate variability (HRV), sleep stages, and readiness scores, helping athletes fine-tune their training and rest cycles.

How to Optimize Your Sleep for Better Running

1. Stick to a sleep schedule – go to bed and wake up at the same time daily.

2. Create a wind-down routine – limit screens, caffeine, and stress before bed.

3. Keep your bedroom cool and dark – around 65°F (18°C) is ideal.

4. Avoid late-night workouts – they can spike adrenaline and delay sleep.

5. Prioritize naps if nighttime sleep falls short – even 20 minutes helps.

Your next personal best might not come from a new training block or pair of shoes—it might come from simply getting more sleep. If you’re serious about performance, sleep is non-negotiable.

Train hard. Sleep smarter. Recover stronger.
