The True Test

So tomorrow I am going to get up early and run 12 miles or so by myself. All of my running friends are on vacation, so I feel like tomorrow as I am running I will find out if I really love to run long distance or do I just just being with my friends while running. I run by myself all the time, but never usually more than 6 or 7 miles so tomorrow will be double that, but I am 5 weeks into my marathon training and I want to make sure to stay on track, so tomorrow is my true test, do I still enjoy long distance running without friends? I guessing I do, but not sure yet. I thought about renting a good movie and running the entire thing on my treadmill, but I think I am going to try outside first and see if I can handle the heat, wish me luck. I cannot wait for all my running friends to get back.
