I think my first century took around 11 hours from start to finish, including rest stops. We stopped a long time at most of the rest stops, way too long. Then I skipped the last one which was a mistake, because I should have stopped there to eat.
My second century was totally flat. I finished that in about 8 hours.
The third one was very hilly. I don't remember how long it took but I averaged about 13.5 mph. Out of 2000 riders I think I was 10th from last to finish, literally.
Then I decided I didn't really like rides longer that 65-70 miles so I don't do imperial centuries anymore.
The hardest thing for me was food, because they were all far enough from home to require a hotel stay, which meant restaurants for the pre-ride dinners and breakfasts, or improvising breakfast (smuggling a toaster oven into the hotel so I could make waffles which I brought with me and kept in a cooler). When you can't prepare the pre-ride meals in your own kitchen, it's harder to make sure you're eating the right foods. I had stomach issues during the first century I did due to the previous night's dinner, and then didn't have enough for breakfast before the ride.
