Hal Higdon:Marathon--Intermediate 1: This premium program is designed for runners training for the Chicago Marathon on October 8, 2017. If you are running a different race with a different end date, you must chose a different plan.
Intermediate 1 features more mileage than my novice programs. You should be a fairly experienced runner to choose it. Every day I will send you emails telling you what to run and offering training tips. For more information, visit the marathon screens on my website: halhigdon.com.
