You do realize that a marathon is 26 miles right?
You do realize that as a first time runner is it HIGHLY unlikely that you'll win the marathon to get the $1 million prize?
Losing 60 lbs in 2 months is unreasonable.
Running and winning a marathon in 2 months is also unreasonable.
If you want to lose weight and train to run a marathon, I think that's an admirable
goal. There are many people here who have lost far more than that and many people here who have run marathons. But I suspect all of them will tell you that they didn't do it in two months.
I'd suggest that you start by reading the sticky posts in the various forums here - learn about
nutrition and proper exercise. That will give you a place to start.
