Can a Woman Break the 4-Minute Mile?

Breaking Barriers in Running
Breaking athletic records has always captured the imagination of sports fans. One of the most iconic records is the sub-4-minute mile. Since Roger Bannister broke that barrier in 1954, no woman has yet managed to do the same. The current women’s world record for the mile is 4:07.64, set by Faith Kipyegon in 2023. This new study explores what it would take for a woman to finally run a mile in under four minutes.
A Look at the Numbers
Right now, the gap between the current record and the magical 4-minute mark is just 7.65 seconds. Researchers analyzed how fast women’s mile times have improved over the years and predicted possible timelines. If the current pace of improvement continues, a sub-4-minute mile could happen as early as 2030—or as late as 2065, depending on various factors like training, talent, and support.
Why Hasn’t It Happened Yet?
Women have had fewer opportunities and support in long-distance running compared to men. For many years, people believed running long distances could harm a woman’s health. This limited participation and delayed progress. Even now, fewer girls continue into elite sports after puberty due to changes in their bodies, social pressures, and lack of tailored training programs. These challenges contribute to the slower pace of record-breaking performances in women’s running.
What Does It Take to Run a 4-Minute Mile?
The study outlines three key physiological traits needed for this achievement:
- High Oxygen Capacity (VO₂max): This is the amount of oxygen the body can use during intense activity. A woman attempting a sub-4 mile would likely need a VO₂max between 65 and 75 mL/kg/min—very high even by elite standards.
- Fast Oxygen Kinetics: The body needs to quickly deliver oxygen to muscles. Fast response times mean less reliance on anaerobic energy (which causes fatigue) and more efficient use of oxygen.
- Strong Anaerobic System: Since a mile race is run above maximum oxygen capacity, the body must also rely on energy systems that don’t use oxygen. This leads to high lactate levels in the blood, which only top athletes can handle.
Other Performance Factors
Speed and endurance are only part of the equation. Other elements that matter include:
- Critical Speed (CS): This is the top speed an athlete can maintain steadily. A higher CS means better endurance.
- Anaerobic Reserve (D’): This is the extra burst of energy available above CS for short periods. Both CS and D’ must be at elite levels.
- Running Efficiency: Though not a top factor for such a short race, minimizing wasted energy at high speeds still helps.
- Maximum Sprint Speed (MSS): This ensures the athlete has a speed “buffer” to maintain the race pace under fatigue.
- Psychological Strength and Pacing: Elite runners must control their pace precisely and stay mentally strong through the pain.
Can It Happen Soon?
The study concludes that no female runner today has the exact combination of abilities needed to break the 4-minute mile. However, we are getting closer. More women are running fast, and with better training, pacing support, and science-backed recovery tools, the dream is becoming more realistic.
Advances like aerodynamic clothing, pacing lights (like Wavelight technology), and smarter altitude and strength training could all contribute to success. Even better track surfaces, optimized race times, and nutritional supplements might give the future record-breaker the edge she needs.
Conclusion: Closer Than Ever Before
The first woman to run a sub-4-minute mile may already be training somewhere in the world. As the science of performance improves and more women are supported in their athletic goals, the gap continues to close. This study provides hope—and a clear path—toward breaking one of the last great barriers in track and field.
