TRI TOP FROM BLACK TO WHITE

I struggle with heat and humidity. I sweat A LOT. I completed 2 Sprint T's last year, and although my endurance is at least fair (maybe even good), I did poorly, horribly struggling with heat and humidity and sweating (North Carolina in July and August).

So I am making what I think are some rational changes. If these or others changes you might suggest don't work, I best not race at all. I overheated on my last race, became a little disoriented, but finished. In fact, despite realizing I should have stopped, once started nothing would keep me from finishing (you know what I mean).

CHANGES:

Helmet from black to either white or silver. Easy fix.

Black Tri top to white. I'm thinking of dying the garment as a cost-saving, Either with bleach or white dye. Any thoughts if this is a good or bad idea?

Black Tri bottom to some lighter color. I know white is inappropriate. Perhaps light yellow.

Much more fluids. A least double what I used in my first 2 races.

Salt tablets before and during the race.

A much heartier breakfast with more quality carbs, such as an extra helping (or two) of oatmeal.

Quick energy carbohydrates on the race. Fig bars? Apple juice?

All suggestions welcome. I love the sport but want to stay healthy. No romantic visions of being a super athlete or running a full ironman under 9 hours. I'm happy with sprints, the people who race, and gradually improving my personal best time.

And, I've fallen in love with swimming!
