How many miles should a high school cross country runner be running in a week?

At the least run 3 miles each day Saturday is an easy day and take Sunday off. With this you should be running about 16-17 miles a week.

^wrong. im a decently fast HS runner (17 minute 5K as sophmore). You will want to be putting 30-40 miles a week. take 1 day off. Have 2-3 days of workouts. easy days before/after races and long runs on the other days. If you are in HS your coach should know something about what you need to be doing. 16 miles a week will not make you faster.
