Right. I get up each morning and go running, Sometimes (usually when I am getting up), it feels like it might be easier to run when I get home after work. I have heard people say (and it sounds plausible) that running in the morning puts up your basal metabolic rate throughout the day, thereby, like compound interest, increasing your "return". If you run at night, do you get the same effect? Or, does going to sleep negate the "trailing" effect of running? Not sure. Anyone have an idea (there must be a small horde of PTI-trianed people out there who know more about this than me!). Cheers, FF.
