Average... for anyone? That's a very good question and one that's also difficult to determine.
However, I ran high school Cross Country this year, and I know about some of the athletes' times...For girls, those who run 5k between 15 and 20 minutes are some of the fastest. Other very good times range between 21 and 24 minutes. However, in Cross Country, the times for girls range from about 16 minutes to 35 minutes.Guys in high school cross country often run it somewhere between 16 minutes and 30 minutes.
However, there are much faster... such as Olympic athletes, getting times such as 14:16 (for women) and 12:37 (for men).
But the average person who doesn't run every day or is not in top shape is a different story.
