Running requires not so many equipment, but a good pair of running shoes that suit your foot it's necessary to reduce the risk of injury.
You should stretch before each run. Keeping your muscles flexible is important to avoiding injury and overdue stress on your body.
To stay motivated, look for a good, energetic music or find someone who will be running with you to hold you accountable.
If you want to check and improve your scores, find a good running aplication to see and improve your results and share it for everyone. I use Endomondo, which is absolutely great, because they offer you also many different challenges.
Remember! A short, slow run is better than no run! You are still beating everyone on the couch, keep up your spirits!
Good luck!
