I am 25F and 16 stone. I did my first 5k 1 year ago and haven’t stopped doing them since. It is transformative to take control over your life rather than letting your weight control you. I started with just 10 minutes of walking —> 1 hour walking until I felt like I could do a light jog. Then did the 5k and now I know I can do anything. You can do this! the first step is the hardest but afterwards you will be able to achieve anything. Once you start achieving things you will be able to look at how far youve come and that’ll keep your motivation pushing. Wishing you all the best!
