I am concerned about the potential heat next weekend. For the marathon, would it be crazy to carry my 3L bladder in my vest (as opposed to my 1.5L bladder)? And if I do, should I put 4 packs of Tailwind in it (1 p/ 24 oz)? I know the 3L is heavier but I’ll be moving slowly so I’m not sure it will make much of a difference.
I am also planning on eating one clif blok per mile (alternating between salted watermelon w/ 2x sodium and tropical punch (?) w/ caffeine) and drinking a PH 1500 90 min before the race starts. I sweat A LOT. Like, grains of salt on my face and fingers swelling a lot.
