My Goofy training's going to be a little weird cause I have all these big races between now and Goofy . . . with the added advantage of not being an experienced marathoner to begin with.
9/6 DL 1/2
11/15 RnR San Antonio (My first marathon!)
Then Goofy in January . . .
I'm doing a tweaked plan from Cool Running for RnR SA, with an extra taper week thrown in the middle for DL. Not sure where to go after that to get ready for Goofy but I've heard a lot of people have used Higdon with good results?
Well, I'll offer the disclaimer that this is definitely not something I'd particularly recommend, especially since 11/15 will be your first marathon. Don't underestimate just how much (and for how long) you'll be hurting once it's over. All of that said...
Higdon has plans for doing multiple marathons close to each other, one of which is for an 8-week gap, so that would fit perfectly in your case. He recommends it only for more advanced runners, but it might be a good starting point for you. With that said, though, I've heard a lot of criticisms of Higdon's plans as well, as they work you very hard, and may (moreso than others) lead to overuse injury.
What I personally would do (and let me point out, I'm barely above novice level, having only completed one marathon so far, and certainly my advice should not replace proper consultation with qualified medical advice, etc, etc):
Open up a nice shiny excel spreadsheet and start typing in some numbers.
Plan for basically nothing during the week following the marathon. Then a moderate/short run that Sunday, as you may be getting stir-crazy by then. Assume that you'll be doing your longest back-to-backs three weekends before the Goofy, perhaps shooting for 9/18. Taper for those last three weeks. Weeks 2-4 should build up to the week 5 distances. Use the day before and after your back-to-backs as rest days (sandwich approach). The remaining three days of the week should be one day each of moderate distance/pace, rest or cross-train, and then shorter distance speed-work. If you're interested in seeing the sheet I actually put together, shoot me a PM.
Good luck, and let us know how it goes!
