Well that was my first run in the rain. Actually quite enjoyed being out in it, until the very end when it became absolutely torrential!
As for the run itself, I found the first 3 mins pretty tough until I remembered to slow down! Then it wasn't too bad.
My legs are fine, it's just my breathing - sometimes I don't seem to be able to get enough breath. I've tried Laura's technique of breathing in for 4 then out for 4 but I find that makes me run faster.
Hopefully by slowing down my breathing will sort itself out over the coming weeks
