PLUS: Hal Higdon's 10-Mile--Intermediate: This 10-week Intermediate Training Program was designed to be used by runners preparing for a 10-Mile Run. My picture of an Intermediate runner is one who wants to improve his or her performance. You should be running five to six times a week, averaging 15-25 miles weekly training. Each day I will send you an email telling you what to run and offering training tips. For more information and directions, visit my website: halhigdon.com.
