I'm doing the same.  Several of us have monthly marathons planned, so you're not the only lunatic out there, don't worry

MCM last weekend and San Antonio coming up Nov. 15th, then Vegas three weeks after that.

I use the marathon as my last "long run," then ran 13 yesterday, will do about 8-10 next weekend, then marathon the next.  I've had several injuries recently, so I'm taking it pretty easy otherwise.  And don't expect a great "time" at each marathon if you're running them this close together.  Though you may surprise yourself.  I BQ'd at Austin three weeks after running the Houston Marathon.

Good luck and enjoy!  Most importantly, if this is the first time you're doing this, don't set a time goal and let your body rest in between.  You won't forget how ot run, I promise.

3 marathons in October

3 marathons in November

2 or 3 marathon in December

3 marathons in January

2 or 3 in February

2 or 3 in March

maybe just one in April?

No big thing.  I don't run much during the week, just half an hour a day if a can.  I don't train.  I try to do at least a 13 mile run on the weekends with no marathons.

On marathon weekends I just go out and run for 4 hours or so.  If I am lucky someone hands me something to drink every couple of miles.

If you have pain, then the body isn't completely healed.  I always have something hurting.

I have PR'd the weekend following a bad marathon. 

We have run several doubles (2 marathons in 1 weekend).  We might do one in December.

My goal is to run the best I can at all times since I can't control the weather.

Yes - You are nuts and it may get worse.

Congratulations on your finish!  And lessons learned.

~15 minutes faster than I usually run! Congrats!
