Distance runners should be running 4-5 days per week at this point. Beginners should try and run at an even pace for 20 minutes, building time as you begin to feel more comfortable.
Returning runners should be running “LSD,” or Long, Slow, Distance. The idea here is to get the miles in at a reasonable pace. 5 Days per week is fine, and you should be running anywhere from 4-6 miles each run. One run per week should be a longer run.
