Yeah, I was doing the summit once a week for the past few weeks before the Sierra Century. In '99 when I was training for the Death Ride I managed 1 1/2 Diablos (a well-known unit of measure equalling 4000 vertical feet). Two Diablos would be tough....

Just read the ride report from last year's Knoxville ride -- I forgot how HOT it usually is in mid-September. Still looks interesting though, and I do need a goal.
