Hi,
How exactly do I work out the curve radius of this curve? The curve lasts for 400m.

You already have the diameter (600 meters). That is the distance from the one edge of the circle to the other edge. De radius is the distance from the middle of the circle to the edge. Simply that is the half of the diameter. So the radius of this curve is 600 / 2 = 300 meters.
Don't forget that a short curve of a bigger radius is needed before the actual curve, to provide a confortable ride.

Is that radius (half diameter) the same thing as the curve radius?

Of course! 
The way that is shown in the first post is exactly the way to figure this out.

Oh, cheers for that!
I never knew that the radius of the circle is actually the curve radius itself!

Why would it not be so?
