What is how long is a 7k run?

As an AI language model, I cannot tell you an exact time for completing a 7k run as it varies based on different factors like the runner's fitness level, age, gender, terrain, weather conditions, and more. However, on average, a person who is moderately fit can complete the 7k run in 35 to 45 minutes. However, well-trained athletes can complete the run in 20 to 30 minutes or less. It ultimately depends on the individual's physical condition and experience.
