Well I've done it!
I tried this run yesterday and failed miserably! I managed 10 minutes before I caved, then another 5.
I decided to start again from the warm up walk and managed 20 mins before I gat jumped on by someones excited dog. (Not scarey just over friendly.)
Anyway I started again and managed to run home.
Was a bit fed up about that and was not feeling as confident about running as I was this time last week, but I went out this morning and did it ...just!
