First time past 3 miles

We just finished our first 4 mile run this morning. It's the longest I've ever done and I was able to run the entire thing!! In high school, I was on the cross country team. I don't I ever comleted a 5k without walking, even after months of training. We've now been working for about 4 weeks and I'm already at 4 miles! I'm very excited.  This morning before our run, I took Want More Energy? (a vitamin supplement), made an effort to drink more water and ate a piece of bread before today's run. Michelle and I were both able to do the whole thing and kept up good conversation while doing it.   I'd like to increase my speed some. I am averaging 12 minute miles. However, I am able to keep running while at this speed, so I'm not sure if I should.

We had a nutrition clinic afterwards and learned about a product called Mila. I'm interested to try it with some coconut water, which I am going to start drinking more of. Apparently, coconut water is better for hydrating than water... no wonder people always tell me to take it for my hangovers! Guess what I'll be having before going out next time?!?! Haha, actually, since we've started training, I have very little time or desire to drink alcohol. It costs too much the next day. Maybe Saturday nights though, because Sunday is a rest day. I've definitely become an old person on Fridays though! But today, that paid off :)
