Today's weigh in before run: 244.8.
Ugh. That means I am up 2.6 pounds.
For kicks and giggles I weighed myself after running (didn't take water with me) and drinking a Vernors when I returned home.
Weigh in after run: 240.4.
So the only reference I could find on the weight of sweat was 1 liter or sweat weighs 2.2 pounds. Which is great because it divides evenly into the 4.4 pounds I was missing. Hard to believe I sweated a two liter worth. (A two liter is a few ounces more than a half gallon).
I guess what I am saying is that when you get to your longer runs, hydration is a must. So invest in something that can carry water.
However, you don't need to pack a 2 liter with you. When you are running you'll need to take constant sips. Any more than that and you hear water sloshing around in your stomach. It tends to make you a little sick and will slow you down. Drink just enough moisten your mouth. If you find you've taken too much into your mouth, your better off spitting it back out.
I only carry a bottle that hold 20 oz. I use water on my shorter runs and Gatorade (watered down) on my longer runs. Have really never been into the gels or energy pack you can get.
So at what point do you need to take something with you? It all really depends on the temp outside and the degree of how much you push yourself. The rule of thumb is any workout lasting over 90 minutes. But, I would say during the heat of summer, anything over an hour is a good idea.
