Ever since I have been increasing my base from 25 MPW back in December to recently 40MPW this past week...<br><br>
I do not sleep well any more... AM I just getting more natural energy or what? anybody else.

What time of day do you usually run? If you're an evening runner, it takes a lot longer than you might think for the endorphins to fully drain from your system, allowing it to start shutting down. I think the general rule is you want to be done running at least 3 hours before bed time.<br><br>
Do you monitor your heart rate? If your resting heart rate has increased recently, you might be overstressing your system and might want to take an easy week.<br><br>
Have you changed your dietary habits recently? Often without realizing it, we'll slack on our nutritional choices when our mielage increases. A soda before bed might be the issue.

I made a similar shift in mileage starting in the Fall and also suffer from bad sleep. However; it typically depends on when I run. If it's after work, I'm eating late and generally more wired, which is a bad combination. The short, dark, dreary days don't help either.

This happens to me when I don't mix in enough recovery / easy running in while base building. Too many hard workouts while increasing mileage maybe?

This can be a sign of over training. Make sure you have built in enough recovery days and weeks. It might be time now for a recovery week if you've been steadily increasing your mileage without a step back.<br><br>
