That's quick. I did my first century yesterday and the actual ride was about 11 hours. I didn't do any planning at all except for the route, which was pretty straight forward staying on one major road. I ignored to look up the elevations and assumed the ride was going to be mostly flat but I encountered 10-12 mini hills between mile 80 to 86. Walked my bike halfway up a couple of times. These hills were approximately quarter mile runs. Around mile 65 was when I was slowly hating the ride. But damn, the train ride home and getting home is the best feeling...I killed a pork french dip sandwich with blue cheese, a slice of apple pie, and iced tea in 5 minutes.
Time was the largest stressor because I had planned to take a train back at a certain time and didn't want to miss it. I had to force going somewhat faster on some of the uphills even if my legs were tired and slowly showing signs of cramping. Towards the end of the trip, I took it easy on the flat areas.
pretty pleasant ride. I rode on delmarva (delaware/maryland/virginia). There's always a huge shoulder (which has bicycle lane indicators in it) and the view was great (forest on one side, ocean on the other). Riding through ocean city, maryland was kinda annoying, beause of all the lights, but again, I was riding on a moderate highway and had an entire lane to myself. Other than that I stopped half a dozen times at 711s or whatever to refill my water and gatorade (it was close to 90 degrees that day, but not humid).
I got home and went out to dinner at a brewpub (dogfishhead) and I felt pretty amazing.
No flats or mechanical problems helped a TON.
The ride was pretty comfortable, with no major aches or pains (i slathered myself in chamois butt'r). I did feel a little impotent when I got home though.
