Do Ultrarunners Sleep? Sleep Strategies During Races

For most sports, the rules are simple. You push hard, rest harder, and aim to maximize performance with equal parts skill and recovery. But ultrarunning flips all the conventional rules on their head. When races span 50, 100, or even more miles over 24+ hours, one of the most burning questions is this: Do ultrarunners sleep, and if so, how?

Sleep (or the lack thereof) makes ultrarunning one of the most mentally and physically demanding endurance sports. It’s not just about who can run the farthest or fastest but also about who can manage their body, mind, and energy during prolonged exertion. Sleep plays a critical role in this delicate balancing act.

This guide explores the effects of deprivation, efficient rest strategies, and recovery solutions for ultrarunners. Whether you're preparing for your first ultra or attempting a multiday race, these tips will help you tackle the challenge of running while fatigued.

The Science of Sleep Deprivation in Ultrarunning

Discover how lack of sleep impacts ultrarunners during extreme endurance events. Learn about the physical and mental effects of pushing beyond limits.

What Happens to the Body and Mind

Lack of rest disrupts nearly every system in your body. Without enough downtime, cognitive functions like decision-making and focus decline. Physically, the body struggles to repair muscle damage, balance energy levels, and regulate temperature. Over time, this leads to slower paces, clumsiness on technical terrain, or even injuries.

Rest is like a reset button for your body. Without it, fatigue builds up, making everything feel harder. Decision-making suffers too—ultrarunners can miss critical trail markers or fail to hydrate properly, derailing their race.

Impact on Performance

Studies show that long periods without rest reduce reaction speed, VO2 max, and microsleep. Even hallucinations can occur during multiday runs. It’s no surprise that ultrarunners rank “managing rest” as one of the toughest aspects of the sport. But don’t worry—strategies like napping and preparation can help.

Napping Strategies During Ultraraces

Learn how to optimize rest for better performance during ultraraces. Discover tips to stay energized and finish strong.

Timing & Duration

Napping is a tactical move for ultrarunners. A power nap of 10–20 minutes can work wonders for quick energy restoration. Planning naps for natural low-energy dips (often in the early morning hours between 2–5 a.m.) is particularly effective.

For longer races such as 200-mile events, some athletes opt for "wake-me-up-at-all-costs" 30- to 90-minute naps. These naps occur off-trail in aid stations, tents, or even makeshift spots like park benches.

Real-Life Examples

Courtney Dauwalter, renowned ultrarunner, noted using micro-naps of just 90 seconds during her multi-hour events. These short bursts, combined with mental willpower and a strong pacing strategy, have helped her win some of the most grueling races in the world.

Pro Tips for Effective Napping

• Pack earplugs and an eye mask to block out noise and light.
• Set an alarm to avoid oversleeping.
• Nap in aid stations to stay safe and avoid getting lost.

Sleep Banking: Preparing for Deprivation

Sleep banking means “stockpiling” rest to lessen the effects of deprivation during a race. Studies show that increasing your rest duration for several nights before an event can boost alertness and endurance during restricted conditions.

How to Practice Sleep Banking

• Aim for 1–2 extra hours of rest per night for the 5–7 days leading up to the race.
• Maintain consistent, high-quality rest by keeping your room cool, dark, and quiet.
• Avoid screens and caffeine an hour before bed to get the most out of your downtime.

Think of sleep banking as an ultra-endurance runner's secret weapon, creating a buffer to handle the upcoming deprivation storm.

Caffeine and Other Stimulants

Explore how caffeine and other stimulants affect energy and focus. Learn their benefits and potential drawbacks.

The Pros

Used responsibly, caffeine can provide a welcome boost in energy, focus, and alertness. A well-timed cup of coffee or dose of caffeinated gels is often enough to shake off the cobwebs and push through mental fatigue.

The Cons

Relying on too much caffeine can lead to jitters, stomach issues, and an eventual energy crash. When sleep-deprived, overstimulation can also cause heightened anxiety or exacerbate hallucinations.

Guidelines for Use

• Start small with caffeine intake, typically 100–200 mg per dose.
• Time your caffeine consumption a few hours before energy dips occur.
• Avoid caffeine in the hours leading to a planned nap to ensure deeper rest.

Pro tip: Experiment with caffeine during training runs to learn how your body reacts, ensuring no surprises come race day.

Mental Strategies for Coping with Sleep Deprivation

When sleep deprivation sets in, mental toughness becomes as important as physical training. Here are some strategies to help you stay sharp:

Stay Focused

Adjust your goals to smaller, tangible ones—for example, aiming for the next aid station rather than the entire finish line.

Manage Hallucinations

Hallucinations are common in prolonged races. Stay calm, recognize what’s happening, and rely on pacers or teammates to help ground you in reality.

Break the Monotony

Introduce variety through music, podcasts, or changes in terrain (when possible) to keep your brain engaged.

Mental preparation is half the battle. Build visualization and mindfulness techniques into your training to simulate race-day conditions.

Recovery Rest After an Ultrarace

The period after an ultra is critical for recovery. Your body and mind need time to repair and reset, and quality rest is the most powerful tool here. Neglecting it can delay muscle repair, reduce immunity, and increase injury risk.

Rest Optimization Tips

• Create a cozy, dark environment free of distractions for post-race nights.
• Take long naps during the day if nighttime rest feels disrupted by sore muscles or adrenaline.
• Gradually return to your normal routine, but don’t rush. Prioritize downtime for at least a week.

The more time you dedicate to recovery, the sooner you'll bounce back stronger.
