Wasn't looking forward to running in the heat today and just felt as though I was boiling running around the pavements with no shade. I decided to run to the woods and then give up. Once I got there I had a slight revival under the shady trees, but was really feeling the heat and couldn't face a hilly run back so I did quit after 20 mins I have annoyed myself giving up so close to the end of the run! Grrrrrrrrrrrrr. Hope to try it again on Sun.
