What?

I'm just biking in it.

I got this long sleeve white Zensah compression shirt. Holy ****, that thing is cold! My arms are FREEZING! Luckily I'm wearing a Pearl Izumi screaming yellow Attack jersey over it, which helps a bit ... it's a bit muggy, but it breaths way better than the rain jacket (which is great in rain, and on cold mornings). I'm surprised I'm colder with the compression shirt than with bare arms.

I have this 3L camelbak filled with Nuun, and occasionally a little ice. I tried Kona Kola, with 80mg caffeine per 8oz ... screw that. Water, salt, stim... no, forget the stim, must have sugar with stim (sugar is good anyway) but not putting that in my camelbak.

Besides, the Kola is too heavy; I'm sticking with Lemon Lime, Orange (Orange/Ginger in the case of Nuun), and Citrus Fruit. The light citrus is easier to swallow and more refreshing--as soda goes, I've always found Sprite and 7up to be the most refreshing, with Root Beer the heaviest (but I suspect Pepsi and Coke would be, too, if they weren't such watery crap), and the same has held true for electrolyte tablets. I'm not sure if I want to try the berry stuff.

So, compression shirt and shorts are keeping me cooler than just a t-shirt. I've only gone with loose shorts. A big camelbak filled with lots of water helps; it takes me 2 days with 16 mile round trips (about 32 miles, 4 hours total) to drain it. Electrolyte tablets are excellent, as I sweat out tons of salts. If I'm not sweating, I'm not drinking.
