How much water are we supposed to be drinking? I am a newbie training for my first half marathon. I had taken a couple of days off from running and ran 2 miles today inside on a treadmill and did some strength training to ease back into it all. Afterwards I was very light-headed and nauseated. Could this be from dehydration?

It could be dehydration but I think strength training causes you to burn lactic acid (or some sort of acid) that can make you feel nauseated. I get light headed from overheating or stopping without gradually lowering my heart rate. Make sure you have a sufficient cool down. I, too, am training for my first half marathin. Where and when is your race? At what point are you in training? I just started running about 6 months ago, ran my first 5k and June and am planning a half marathon in October. My long run this week was 5 miles so I have quite a ways to go!
I've heard the recommendation of 1oz of water per 2 mins of effort. So a 20oz bottle of water will last for about 40 minutes... Of course, this has a lot to do with how hard your effort is, how hot it is, etc.
You might either be dehydrated or were lacking enough fuel throughout the day for the workout. That doesn't seem like an intense workout, but if you didn't have anything before exercising in the way of energy (food) and don't drink much water throughout the day, those are the culprits. I would try to workout next time and drink water ahead of time throughout the day and see what happens. If you still feel sick, then maybe look at what you ate that day before working out, if anything.
Water is important, always, and no matter whether you walk, run, bike and even swim you should always have a full bottle of water with you.
I had been a "walker" for years and just started running but mostly outside. I live in Florida, which is not all that great. Yes it is almost always sunny but the hot and humidity is bad. When I walk at 6am it is already at 78 degrees and the humidity is up there!!!! When the weather is bad then I resort to going to a local gym and going on the treadmill. I had to cover the console because I could not stand watching the slow travel miles! The first time I got off I was dizzy and wobbly. Now I do a cool down and slow down the speed to 1.5 mph and it is better. Not sure if that is your same feeling.
When you walk outside, the time running passes faster because you have other things to focus on; there is traffic; people to say good morning to; houses to look at; check out the gardens, look at the lake,and the next thing you know you have travelled 3 miles or more.
Keep it up, it is all for YOU and anything you do for YOU is worth it.
