Yes. Poor sleep raises running injury risk across recreational, endurance, and youth athletes. Poor Sleepers means runners with consistently low-quality, disrupted sleep, and they face markedly higher injury rates than steady sleepers.
In a 2025 survey of 425 recreational runners, Poor Sleepers were 1.78 times more likely to sustain injury. Their probability of injury within 12 months reached 68%, according to the University of South Australia report via Newswise University of South Australia report. The pattern appears in teens and elites as well.

How strong is the link for everyday runners
The recreational running study identified four sleep profiles: Steady, Poor, Efficient, and Fragmented Sleepers. Only Poor Sleepers had significantly higher injury risk than Steady Sleepers. Efficient sleepers and fragmented sleepers did not show the same increase.
That distinction matters for runners. Occasional restless nights differ from an ongoing pattern of poor sleep. The higher risk sits with runners who sleep badly on a regular basis.
How much sleep protects young athletes
Among 112 adolescent athletes followed for 21 months, those averaging under 8 hours per night were 1.7 times more likely to sustain injury than those sleeping 8 or more hours, as reported in the Journal of Pediatric Orthopaedics PubMed study record. A separate Swedish high-school athlete group showed similar protection from longer weekday sleep. For adults in endurance sport, 7 hours looks like a turning point.
In a 52-week study of 95 endurance athletes including runners and triathletes, under 7 hours per day predicted increased new-injury risk using a 14-day lag, while over 7 hours predicted reduced risk, according to the Journal of Science and Medicine in Sport record prospective endurance-athlete study. Risk does not rise the next morning alone. It builds over days.
Why heavy training makes short sleep riskier
Sleep loss rarely acts alone. In 496 adolescent elite athletes, combined increased training load plus decreased sleep produced an injury hazard ratio of 2.25. That combined risk exceeded low sleep alone.
Think of a runner adding mileage while cutting sleep for work, school, or early workouts. Recovery drops at the same time stress rises. The body then has less capacity to absorb hard sessions, hills, or back-to-back runs.
What runners can change this week
Lead researcher Jan de Jonge advises runners to treat 7-9 hours of consistent, good-quality sleep as injury prevention, as reported by Canadian Running Magazine. Regular bedtimes and limited evening caffeine and screens support that goal. Use these checks for the next two weeks:.
- Keep bedtime and wake time within one hour daily, including weekends.
- Stop caffeine in the afternoon and evening.
- Dim screens and bright light in the last hour before bed.
- Match hard training days with full nights, not short nights.
- Track sleep, mileage, and niggles to spot your own 7- or 8-hour threshold. Studies rely on self-reported sleep and recalled injuries and cannot fully separate sleep from training volume, stress, or prior injury, as reported by SciTechDaily.
