Heat

We've had highs consistently in the 90's for almost a week, and the forecast doesn't look like it's going to change anytime soon.  I'll need to get used to it.

I read last year that you should expect to add 20 seconds to your mile time for every 5 degree temperature increase over 70 degrees.

I'd say that is about right... while running itself burns energy, so does the body as it attempts to stay cool.  Distance training is as much about teaching your body to burn energy more efficiently (think of better MPG in your car) than anything else.  These hot workouts force the body to work harder which is great for training purposes... let's just hope it's nice and cool in Chicago on October 10!
