Running Exercise and Inability To Sleep

One month after running the 2008 Nairobi marathon I have noticed that in the last month my sleep has been better than the month leading to the marathon. This days I sleep longer unlike the last month leading to the marathon when I used to wake up at a frustrating 4.30 am, two hours early before my desired wake up time.

When I noticed this change in sleep pattern I decided to find an explanation. I found this article at wikipedia on overtraining that states  “Training at a high intensity too frequently also stimulates the central nervous system (CNS) and can result in a hyper-adrenergic state that interferes with sleep patterns.” 

According to that statement too much exercise may cause sleep problem. In the last month I have not been running, this lack of physical activity explains why my sleep is good.

My next marathon will be next year and I plan to crank up my training. I don’t think a runner should cut down on his weekly miles just because he is losing a few hours of sleep. To be a successful runner you need to make lots of sacrifices and that includes missing a few hours of sleep. A runner will get enough sleep after a race and like Benjamin Franklin said “There will be a lot of sleeping in the grave

    Hi Constantine. First off, congraulations on the marathon. Terrific! I’ve noticed that my sleep pattern is now back to normal after a 16 hour time difference (both directions). It takes close to a week to get the sleep pattern back afterwards.

    I agree that the same thing happens after a major race as well.
