Marathon Training Week 2

Today's run was just 3 miles. It is the shortest run of the week. For some reason, these are usually the hardest for me. Today, it wasn't that bad. I decided to do this outside, even though it was getting dark. It was a pretty hilly run, but I had my best time for a 3 mile stretch so far. This was run number 6, and marked 23 miles of training.
The knees were bothering me a little bit after this run. There were more hills than on my Monday route. It might be time for new shoes. I also had some shin splints from the 1.5 to 2 mile stretch, but they went away on the last mile. I will be running the same route in the morning, only I will be running 4 instead of 3 miles, so I will be watching to see if the shin splints come back.
The increase in my running and the weight watchers has sent my blood sugars plummeting the past few days. I've experienced more lows than I ever have. I think it will be time to adjust some medications soon, which is exactly why I am doing this.
