Looking at the map on the ACTC website, they look about the same - the descriptions you found are for this year's ride. The only change I can see is in the 100 or the 128 milers, it used to go on the Coyote bike path, and up Metcalf. Now it's off the path I think, and down Metcalf.

Here's the map - the shortest route is in yellow. It's a very pretty ride!
