I have just done it... The run... I did about 5km in 35 minutes, and I am feeling a whole lot fresher than I have after my last few shorter runs. That might be because of the weather. I do not know. But I feel fairly good at the moment... Cooling down for a few minutes before a cool shower.

I tried the breathing exercises mentioned earlier but they were not much use since I tend to take a number of steps between breaths, and also I tend to exhale slowly, at least at the beginning of the run. My fitness is certainly improving. I just need to keep this up.

Anyway time for a shower.
