You don't say what camera you're using, but generally, a 70-200 should be fine if you are using a full frame camera. It is not possible to make a better recommendation without knowing how high they will be.
The first was @185mm, 1/2000, F4. The second was @300mm F4. The last was @600mmF4. You don't need a particularly fast lens if your panning skills are good.
