As the hole accretes mass it's radius grows at a certain rate, which I believe will always be less than C. But the distance between any two points on the Event Horizon grows more quickly because surface area increases faster than radius

Is davidmac implied, the surface distance between points on a (euclidean) sphere grows only in proportion to the radius. If you double the radius, you quadruple the area, but only double the distance of two points on the surface.

All this is Euclidean geometry and doesn't apply to the horizon exactly.
