Fitness workout

I started to run about 3 miles and after three months I reached on my track and go for the  7 miles target. I was doing it from 4 months. But now I want to reach up to 10 miles. Can anybody help me how can I do it. Is it possible to take short break while I am running? Help me please.

Thank you

i run 3 kms and i sprint 15 times which contains around 10 seconds each sprint, and one more thing i take 25-30 sec of rest after 8-9 sets of sprint then i hit the gym for abs workout.  is it good enough for this 28 days to six pack abs program? though i feel like its good enough but i still need your suggestion.
