The best time to run depends on individual factors, but research suggests that late afternoon or early evening often provides optimal performance.
Factors Influencing the Best Running Time
Several factors influence the ideal time to run:
-
Physiological Performance: Our body's oxygen and lung capacity peak in the evening, potentially allowing for longer and faster runs. [Reference: Our body's oxygen and lung capacity are at their prime in the evening, meaning you will likely be able to run longer and faster at night compared to morning. Running more consistently. You are likely to run more consistently in the evening than in the morning as it is easier to fit into your daily routine.] Also, studies show that endurance and strength peak in the late afternoon to early evening. [Reference: According to researchers, endurance and strength peak in the late afternoon to early evening. However, studies also show benefits to morning runs.]
-
Fat Burning: While some sources suggest morning runs may burn more fat, this is often counteracted by the benefits of higher performance during the evening. [Reference: a morning run has a slight edge over the evening run because of its higher fat burning capacity.] The overall caloric expenditure might be higher during an evening run due to increased performance, outweighing any potential slight advantage in fat-burning percentage.
-
Schedule and Consistency: Ultimately, the most crucial factor is consistency. Choosing a time that fits your schedule and makes running a sustainable habit is key. [Reference: The most important factor in choosing what time of day to run is to pick a time that works with your schedule, energy levels and goals.] Evening runs are often easier to fit into a daily routine. [Reference: You are likely to run more consistently in the evening than in the morning as it is easier to fit into your daily routine.]
-
Environmental Factors: Morning runs offer the benefit of less pollution in some areas. [Reference: The best time to go for a run is in the morning because at that time the pollution level is less than other time you will get fresh air as well …] However, this should be weighed against personal preferences and the overall benefits of peak performance times.
Optimal Running Times: A Summary
- Morning (6–7 am): Potentially better for fat burning, and less polluted air in some locations. However, may be less ideal for peak performance.
- Late Afternoon (3–5 pm): Body temperature and core body temperature are often higher, increasing performance.
- Evening (6–8 pm): Generally considered the best time for peak performance due to increased lung capacity and other physiological factors.
The ideal time to run is the time you can stick to consistently. Experiment with different times to find what works best for your body and lifestyle.
