Hal Higdon: Marathon--Intermediate 1: This is my Intermediate 1 Marathon Training Program, one step up from Novice 2. It is designed for runners who may have used my novice programs to run their first marathons and who are now looking to increase--at least slightly--their training levels hoping to improve their Personal Records. It is not recommended for runners doing their first marathon. If that is you, check out the descriptions of the novice programs before deciding which program to purchase. Each day I will send you emails telling you what to run and offering training tips. For more information and directions, visit the marathon screens on halhigdon.com.
