Not much to add . . . . lots of great advice in this thread.

I did the Davis Double three times with times of 14 hours, 13 hours, and finally, 12 hours. I was in my mid-40's at the time, and had had 2 heart attacks and a quad by-pass.

My training included a 110 mile ride every Sat for the 2 months leading up to the double, and several 30 mile rides during the week. Three and two weeks before the event I did a 140 and 160 mile ride, respectively.

As others have said, pace, fluids, and fuel are the keys. And, as others have also said, don't get caught up in a group going too fast. I did that one year and was averaging 20 mph through 120 miles. Then I bonked and had to limp in for 80 miles. It was devastating.

Regarding stops, I stopped around 4 or 5 times just to get water and fuel. I'm not sure there is any benefit to a prolonged stop, or a snooze.

Good luck, man! I'm jealous.
