I am following Jeff Galloway's plan for experienced runners with a time goal. Although I have never run a full I don't have a time to go off of, and Disney races are for fun and not a PR (for me). I am adding in a half marathon or two. The plan goes up to 29 miles

but I am not planning on going that far. I think it's just asking for trouble. The farthest I'm hoping to go is 23, maybe 24. I just did 15 yesterday and that was a challenge. I did 13 2 weeks ago and it seemed relatively easy. That's why I'm hoping throwing in a few half marathons will make the longer runs see more manageable. It really is all mental. And eating better the day or 2 before would have been helpful too.
I like Mr. Galloway, and maybe for the walk/run thing this works, but I would NEVER recommend going more than 23 miles for anyone I cared about (really 20 for most). In my 10 marathons I have never run more than 23 miles in training. I think for most people this could easily have you watching the race from the sidelines. Not sure what the benefit is. Not to mention you kind of spoil the fun of running 23-26.2 as new territory.
Question for those doing the Full. How many runs longer than the half marathon distance do you have planned and how long are they?
I have 5:
My typical schedule (for racing) is:
14, 16, 17, 17, 18, 20, 23, 23, 20, 23, 23, 18, 10, race.
This year I'm racing the half and just planning on having fun at the marathon, so I'm doing kind of a half/full hybrid program:
10 (race), 16, 16, 16, 12, 13.1 (race), 15, 20, 20, 12, 20, 19, 15, 9, Goofy
Keep in mind that for my first two marathons I did:
14, 16, 18, 12, 20, 20, 16, 8, marathon (which worked fine)
Since getting into running, I have seen shirts and postings and such that talk about how people don't know how long a marathon is, or people saying I ran one of those 5k marathon things, etc. And I couldn't believe it - how does a person not know the length of a marathon?
I was embarrassed recently as I was at a big meeting and said one of my bucket list items was to run a marathon with my three daughters (11, 9 and 6 now). One of the staff stood up and told everyone that I had already accomplished that by running a marathon with one of my daughters.

She was thinking of the
Disneyland 5k I ran with my daughter. Nothing like having to explain to everyone that it wasn't true.
