Does Fish Carbo Load?

I welcome back all Marathoners from the sunrise of the Singa Land. It's one hell of an event, I'll tell 'ya. 19,000 full marathoners pounding could have generated enough energy to at least light a 'reban ayam'.

And I know most of you are hardcore runners, but I have a question that has been bothering me. You all know about the benefit of carbo-loading week, or pasta party before your long runs. You even enjoy the indulgence, I would assume.

But what about before our swims? 

Do we carbo-load and hydrate before our (long) swims? 

If yes - when do we start, what food do we consume, when will be the last meal, hydration plan? What would be the food not to consume? Would the food I take and all the food I avoid prior to my runs works the same for swims?

I know for sure my body won't swim with food not 2 hours set in. 

If no - sure or not?

When I picked-up swimming early this year, my morning swims and afternoon getaways were fueled by Gardenia's chocolate loaf, which did give me a 'feel-good, stomach is full' factor, probably from the sugar rush from the cream and carbs. I somehow outgrew them out of health concerns. For now, bananas at my elevenses would suffice.

And since the swim mileage starts to get a little longer than usual, I found my throat burning and dry - and the next best water available is without a doubt not potable.

Geez, how do people swim 3.8km, or 6.5km? Tabik spring pun tak cukup... 

I hope our swimmer/triathlete friends could share and shed some light into this. My thanks in advance.

No Diket - we do not bring our pace note for the swim, bro :D
