I’m sold on Nuun. No, it’s not a swedish nun. It’s these little tablets you drop in water to make it into gatorade. It’s sugarfree, portable, and helps you avoid dehydration. I take them when I sail. I used to have to take bottles of gatorade. Not only was it annoying to have to stock up on the sugary swill, but it was heavy. Now I can drop a few tablets of Nuun in regular half liter water bottles during a race, and I avoid the post-race headache. And they come in these waterproof tubes (like airborne).
