Ultra-running data shows female endurance gap narrows over extreme distances
Amateur race studies show women closing the performance margin in ultra-endurance events, BBC News reports.
The short version
- While male runners lead by 10% to 12% in distances up to marathons, amateur data shows the pace gap shrinks to 0.25% at 100 miles.[BBC News]
- Researchers point to possible physiological traits like fatigue resistance and fat metabolism, alongside milestones such as Jasmin Paris finishing the Barkley Marathons in 2024.[BBC News]
- Experts warn that firm scientific conclusions remain difficult because women comprise only about 20% of ultramarathon starters.[BBC News]
Key facts
- The performance gap between male and female runners averages 10% to 12% in races up to marathon distance.[BBC News]
- An analysis of amateur ultra-running data shows the pace gap declines to 0.25% in 100-mile races.[BBC News]
