If you want to focus on doing well in the marathon, then you need to drop the 5x a week CF habit. 2 days a week is the max I would like to see an athlete doing CF, and I prefer those WODs to not be more than 15 minutes.
As far as eating goes, I train low and race high. I second Bob Seebohar's book. I think it's a better place to start than Paleo Diet For Athletes because I prefer that athletes train on a lower carb diet and race on high carb, wheras PD for Athletes is a train high, race high approach.
Eat higher carb on longer workout days. Best source of carbs are yams, sweet potatoes, then fruit. I use Jay Robb's Yammits when I don't have a sweet potato to eat.
Currently, I am training for an ultra-marathon. No speed work. I am doing great on lower carb, and can run in the fasted state and not use any nutrition for up to 2 hours so far. I do use Purple Wraath before exercise on long run days, which is a BCAA and beta-alanine supplement. When my runs get longer, if I need to eat I will use dried fruit or a Lara bar.
I will carb-load leading up to the race and eat carbs during. That way, I have the best of both worlds: I am optimally adapted to fat utilization and glycogen sparing, so I will burn fat for fuel and my glycogen stores will last a long time. I liken carbs to rocket fuel: not appropriate for every day use, but great on race day.
So, again, pick your goal for the race and find a training plan that suits it. CFE just to finish, or a marathon training plan (loads of them available on internet or through a coach) to RACE the marathon.
Best of luck to you!
As you are training low, how many Grams of carbs do you eat? Do you adjust to suit the workout?
It is not what we take up, but what we give up, that makes us rich.
