person A: Starting to get better at jogging. Last summer I could only jog a couple of miles. Now I'm working up past 5 miles_comma_ to 7 and 8 miles each time I go out. I need to get a lot better with my mile times_comma_ but I'm starting to get interested in the idea of a half marathon.
person B: Wow!  That is impressive!  You must be really prod of yourself!
person A: Yeah_comma_ I am. I mostly just do it so I can eat as many cheeseburgers as I want and not get too fat. But now that it's a little bit more of a realistic possibility to do something like that as an achievement_comma_ it's become a little interesting.
person B: Haha!  That's funny!  I work out to drink and eat bad food as well!  Awesome achievement with your running!  Keep at it!
