I did my run at about 1750 yesterday afternoon. The sun was shining and it was around 21 degrees. I hate the sun on my face or head at any time but could not go back for a cap. First 90 seconds hurt at the end. However I found by looking up and concentrating on about 50 or 60 metres in front of me I improved. I tried varying my breathing and thinking of the benefits of an improved me.
At the end of the final 90 second run I punched the air again. I warmed down again but a bit more movement and stretches to finish off. Just trying to focus on one run at a time.
I push doubts away with the positives this must ultimately be doing me.
