I consider a ride that challenges my mind, body and determination epic. The seven hours of hills, mountains, flats and heat of the Enchanted Circle last week was EPIC.

My century last summer in Houston where the average speed was 19 mph and the ride is flat as a pancake, not at all epic. A 60-80 mile roll through the hills near my house, not epic. So, yes it is subjective but most often I would just say challenging.
