hello der you can definitely take part in the competition
but u need to follow some instructions
for that u need to start running daily
imcrease gradually from 5 to min till maximum time that you will get tired
if you cannot run plz stop der and take rest....participating in a event like dis itself is a proud movement.
before that check ur blood sugar levels and blood pressure carry some amount of chocolate and glucose while running
when u feel hypoglycemic you can have them.
