Training plan for 2 marathons in the fall...3 weeks apart

            I am running the Marine Corps Marathon (marathon #3) and the Anthem Richmond Marathon (marathon #4) in the fall  of 2014 and basically chose Hal Higdon's 18-week Intermediate training plan and then to be ready for the second marathon I repeated the last 3 weeks to make it into a 21-week training plan with small adjustments to week 19 to allow for healing from the first marathon. I am actually starting on week 3 with 27 miles for the week and could not be more excited about this plan.

Notice on week 19, instead of doing a week with 5/8/5/4/ and 12 miles...I will allow myself to do a week with 3/5/3/4/ and 12 miles.
