PLUS: Hal Higdon's Personal Best Training Program: This 30-week Personal Best Marathon Training Program is designed for experienced runners, those who have run two or three or more marathons and who would like to improve their times, to achieve Peak Performance, to set a Personal Record (PR), perhaps to score a Boston Marathon qualifying time (BQ). It combines my 12-week Intermediate Spring Training Program with my popular 18-week Intermediate 1 Marathon Training Program. If you are an experienced runner, you could just as easily access each of those programs and move from one to the other at the end of 12 weeks. But I've done the work for you--and at a lower price for both separate. Each day, I will send you an email telling you what to run and offering a training tip.
