Skills work won't burn that many calories. Running up and down will require the most energy, especially with lots of direction changes. No one can tell you how many calories you're burning as it depends on how heavy you are, how intensely you are running around, and amount of running vs skills work. Any number anyone gives you will be a guess plucked out of thin air, just like the 500 - 1000 kcals I'm plucking out of thin air right now. It's probably somewhere around there.
