My wife and I have bicycle toured close to 25,000 22,000 miles ( my wife corrected my arithmetic), a total of 2 years, in 11 countries during the last 12 years. Our longest ride was 3700 miles across the U.S. in 74 consecutive days. That was an epic ride for us. Another was a 3-month ride in Europe covering 3,000 miles: Portugal, Spain, France, Switzerland, Germany, Belgium, and the Netherlands. We are planning on finishing our ride across Canada next summer, Toronto to Halifax. Actually we consider most our tours as "epic", but for different reasons. I think the mental challenge is also a component of epic rides. On one long tour we encountered 35 days of rain. Some tours are just a little more epic than others

This ride took us from Vancouver, BC to Whitefish, MT. We definitely considered this one "epic".

The ride over Logan Pass in Glacier National Park is consided "epic" by most folks.
