Take It to the Limit One More Time

"So put me on a highway / and show me a sign / and take it to the limit one more time." - The Eagles

Today I ran 16 miles, which is farther than I have ever run at one shot. In the process of training for the marathon, I'm going to keep bumping up the mileage of my long runs, each time taking myself to the limit of where I have been before and then stepping beyond that. I've got to admit that I'm a little sore right now, but I didn't reach my physical limit aka "hit the wall." I'm waiting for that day to come where I have to push through a barrier. After I hit this wall, I wonder where the next one will be. The only one that I've hit in the past was at 3 miles...I just couldn't run 3 miles. It took me about 2 weeks to transition from running 2 miles to running 3. Ever since then, I've never had a problem adding more mileage, but I know that day will come.
