Well done Emski - extremely proud of you! You have some competition as your neice ia also starting out with a running programme. (yes her, the one that usually avoids all forms of exercise unless it involves shopping!)
You will be amazed at what you will be able to achieve, you have the determination so go for it!
As for those who are worried about what they look like whilst running, get your headphones on and get out there - at least you are doing something positive. Choose a slightly quieter street to run down, or a park maybe if during the day.
Good luck!
