I always used to say that I wasn't a morning runner. I tried it a few times & found it awful. However I tried again recently (to stop the sarcastic commenst about running widows) & it's great. I have a glass of water & a tea/coffee, so there's 30 minutes between getting up & going out. I read somewhere that the body takes 20 minutes to wake up properly. I don't eat, but at the weekend before my long run I do eat a bowl of cereal, and wait an hour before I go out.
I believe that it is proven that running early morning is in fact a little slower, & I'm not sure that it would be wise to do any real speedwork early morning, but other than that I love it. This morning was lovely & bright, but cool as well. I ran for just over half an hour, & still left for work just after 7 o'clock. I feel refreshed & full of energy.
