I haven't done it yet either but plan to this year. I'm training for it now. I ride 75 miles a week now and increase the mileage about 10-15% weekly. I will enter a metric century scheduled for April 30 and if that goes ok a full century on my 61st birthday in mid June. both of these rides are in the mid Willamette valley in Oregon.... not as flat as Florida, but close enough. I run 46x17 and am aiming at maintaining a cadence of no less than 80 for a speed of about 18 mph.
If this doesn't kill me, I expect to try the
SEATTLE TO PORTLAND in 2007.
