I have recently lost 30lbs and was training regularly... about 80-100 miles a week. Well I have since hit plateau for two months. My diet was basic, calories in and calories out. I've noticed when I increased my miles (120-150) and intensity I was having trouble sleeping. I would increase my calories to match my work load as well and still having troube sleepling. I have also backed off some of my training and I was able to sleep better. Three days the most. And sometimes cross train. Of course this is effecting my training and I don't want to loos to much fitness come spring.

My question is, could I be overtrained? How long could one be overtrained? How long do I need to back off to go back out and be able to train as hard as I like. This has been going on for about two months off and on? I've been tracking my sleep patterns and I've noticed on high intensity day and long days (4 hours) are the nights that I have trouble sleeping.

Any advice.......
