The Diabolical Double is an extreme epic ride that highlights the incredible beauty and severe terrain of the Allegheny Mountains of western Maryland and West Virginia.

The Diabolical Double was selected in 2009 by Rapha Continental as one of the top 25 Epic Rides in North America and riders unanimously agreed the ride ranked was "one of the most stunning and demanding rides of the summer". At 125 miles and 16,500 feet of climbing, this ride is an extreme challenge on par with any single day ride in the world, including the European climbing classics such as Etape du Tour, la Marmotte, and the classic Italian Gran Fondos. Compact cranks or triples are very strongly encouraged.

The Diabolical Double shares the route with the Savage Century through Checkpoint 3 at mile 59 and then again the final 15 miles from Checkpoint 6 to the finish atop ASCI. Riders may choose to downgrade to the Savage Century at Checkpoint 3 if desired.
