Its easy to find numerous examples of hyperbole in the mountain bike world. The word "epic" has been used so much, often describing things that are in no way "epic", that it has lost its meaning.
That being said, these guys truly had an epic journey. Biking 60 miles into the Alaskan wilderness, then breaking out portable rafts that they carried with them and proceeded for miles on a 34 degree river for 12 hours. They then bushwhacked, hiked and biked there way to visit the bus made famous in "Into the Wild"
I am impressed.
