I don't measure these things, so I can't choose an answer to the poll. I do know that "hilly" has changed for me over the years. The first time I did the Patuxent River Rural Legacy ride, I thought it was really hilly. But now, well it's not flat, but it's not really hilly either.

It's the same thing with ride distance. When I first got a bike after moving to DC, most of my rides were about 10 miles, I considered 25 miles to be a long ride, and a century was just crazy. Then someone asked if I wanted to join him for a ride from Harpers Ferry to Georgetown on the C&O Canal towpath, which is over 60 miles. After that I decided I wanted to do a century. So now for me 25 miles is a short-ish ride, and 10 miles is really short. But I expect that to change in time, and at some point I will be back to thinking that 10 miles is more than enough.
