Hey there!
I have just been reading your thread and think you are doing amazing. I am a personal trainer and nutritional therapist and am addicted to running. I know how hard it can be to battle with the challenges of starting a new diet and new exercise as I deal with this everyday in my job with lots of different people.
Keep up the good work though. It sounds as though you are doing brilliantly. Just remember that - 'no matter how slow your run, you are still lapping everyone who is sat on the couch!!'
