None of us can tell you that. I burn about 300 to 400 calories in a 45-minute spin class, but even with me it varies becuase of a couple of things:
The instructor. There's one instructor that is far better than the others who will always do a good job of pushing us, choosing good songs, and choosing a good "route" for us.
The intensity I choose. The thing about spinning is that you choose how hard you work. If you turn your dial more one week than do you do the next, you'll burn a different amount of Calories.
So, again, nobody can tell you how much you'd burn. Even knowing your age, height, and weight isn't even enough to give you a good guess. Someone can be your same age, height, weight, and gender and if they have different health problems, or if they have more body fat, or more muscle mass... that will affect Calorie-burning.
All of that being said, on the fitness tracker here on SP, you can select "spinning" and enter "60" for the minutes and it will give you a guesstimate as for how many Calories you've burned.
