Training Week 3 in the books

Week 3 of my marathon training is in the books. I completed a 4 mile run this morning, my 4th run of the week, 17 miles run for the week, 48 miles run so far. I took it easy on myself and ran on the flat portion of the trail. I stopped and bought some new shoes after the run, and the man at the store wondered how I had been running on those shoes. Hopefully that will eliminate the shin splints.
The 4 mile runs are definitely getting easier, as is the recovery. This was my fastest 4 mile time so far, even faster than my last treadmill run. The weather has been great the past couple of weeks, I have only had to run inside twice out of 12 training runs. I hope this continues. It was a great way to end the year.
