Marathons, Electrolytes and Fueling

Hello Everybody!

So next Sunday I'm running my first marathon, the Cleveland Marathon. I turned HCRV in the middle of my training and have had some questions but just made do with what I could muster up.

I start my long run mornings off with water and about 15 dates. For fuel mid long runs I was taking GU's and continued to even to this day but have always wondered if maybe I should replace them with even more dates?

In my water bottles for 15+ mile runs I always carried a watered down version of powerade or gatorade to keep the sodium and electrolyte levels up, but also tried watered down coconut water which I found pretty nasty when it warmed up.

Durian Rider or any other experianced 811 / HCRV's, what do you use pre race and during. Obviously carbing up isnt a issue on this diet, but do you guys intake any gatorade / powerade for electrolytes? Up the salt intake outside of celery and coconut water? and what are you guys using for race fuel? Obviously most water stations along the marathon course will only have water + gatorade and gu's, which isnt really 811 friendly I dont think.

All help would be appreciated!
