Some locals also refer to the Horseshoe Loop as the Blue Loop because of the blue trail markings along the route. The trails are usually ridden in one shot, but may be ridden separately - both trails have their own trailhead.
There are a number of small intertwining trails on both the Horseshoe and G8 Loops that may cause confusion to newcomers. Trail markers do exist, but are sparse. Stop by the local bike shops for beta on the best loops or get out and create your own loop by combining the maze of trails found in this area.
