30 seconds off 8 minutes is 6% faster and in a half you're already up close to your lactate threshold but still running very aerobically. I thought 5k is supposed to be way over your lactate threshold and close to your aerobic threshold.
Sorry Emmy. I forget how exposed lone female runners must feel. I just hope that if the policeman had felt you were in any danger he would have explained a bit more.
Definitely getting colder. I ran 10miles on Sunday it felt a bit cold when I left the house in shorts and t-shirt and I assumed it would get warmer.
How wrong I was. Got a full soaking and took me all day to warm up again. Ended up off work yesterday with horrible flu like symptoms that have gone by the afternoon. Wasn't feeling great last week but it seemed to have passed by Friday. Maybe I'm overtraining!!
Don't worry about it. It's a lot more complicated than that. Different foods are broken down at different rates. The energy is absorbed at different rates depending on what you are doing at the time and the state of your hormones.
Your body even works less when you eat less to compensate for the reduced intake and it also works more when you eat more. It'll also store more under certain conditions.
Calories is just a very basic guide.
Anyone who says it's a simple matter of calories in more than calories out equals weight gain really hasn't understood how complex a system the body is. There's all sorts of time lag going on for a start.
