I’ve run a bunch of marathons and ultramarathons and helped a lot of people get started in running.
The most important thing you need to keep asking yourself about overtraining is “is this good pain or bad pain?” If you’re experiencing bad pain, joints and such, you need to stop and take some time off.
You’re still in the ramping up stage, and your chances of injuring or hurting yourself are pretty high if you are not careful. Once you reach the point where you are running 30 miles or more week, or can run comfortably for five miles without stopping four or five times a week you’ve turned the corner.
Your body is still getting used to running. Listen to it when it tells you to lighten up. That being said, if you’re feeling good and not experiencing pain or excessive soreness you’re probably not overtraining at this point.
Typically you shouldn’t plan on increasing your weekly mileage by more than 10% a week.
Go for quality over quantity, and listen to your body. I have a Garmin, and I love it, but I don’t let it tell me what to do. You shouldn’t be walking every half mile if you feel good. You shouldn’t be pushing yourself to finish half a mile if you need to walk before that point.
We all have good days and bad days. I’ve been doing my long with the same guy every Sunday for about five years. Some days he kicks my ass, somedays I’m waiting for him at the car for ten minutes before he finishes. You can hurt yourself by trying to adhere to a schedule you’re not ready for, or hold yourself back by adhering to one you’ve outgrown.
I’d say use your training shedule as a guideline, but don’t be married to it.
Your goal should be to feel good. I feel good when I run, a little suffering releases dopamine and I enjoy it while I’m running.
You should seek to run at a pace and distance that lets you work hard and feel good simultaneously.
You should be seeking that zone. When you find it, that’s when you really start to improve and fall in love with the sport.
Good luck!
