This is a definite wonder of the world. The huge canyon, carved by the Colorado river, is 446km long, reaches up to 27km wide and has a largest depth of almost 2km! If you have ever been (and coped with the heat), you will surely open your eyes to this epic landscape. As usual with this series, you have a choice of 30/100/200km to accumulate in your own time and place by walking/running.
This medal shows off the sheer cliff faces of the canyon with the Colorado river at the base, flowing through. The rock is mixed with the metal colour of bronze, silver or gold, depending on whether you choose to accumulate the 30km, 100km or 200km distance.
