I didn't say anything about a particular speed. My point still stands: you can always average faster speeds if you know you're riding only 50 miles compared to what you'd do to go 100 miles. Just like sprinters getting up to 50mph for short distances, but they don't try to do that for 100 miles.
After about 3 hours on the bike, I'm ready to take a nap and start the rest of my day. I've never been inclined to spend half or all of my day on a bike. Too many other fun things to do.
