If we are doing a tour in Europe, we get there 2-2.5 days in advance. Yes, it's true to get right into the new time zone, but since most flights to Europe are overnight, and I can't sleep much on a plane, even in business class flat beds, I am losing 3-6 hours of sleep. We get there, eat a good breakfast, and walk around, do tourist stuff, have an early dinner and go to sleep somewhere past 8 PM local time. We make a rule not to take a nap; but when we went to Spain, it was like 100 degrees when we got there. We had coffee, lunch, and about 4 miles of walking. We got back to the room, were resting and we fell asleep. When we woke up, it was 9. Problem was, we didn't know if it was 9 AM or PM! It's still quite light out in Spain at that time in late May and we couldn't tell from the TV. Not sure why we didn't go look at our phones right away, but there was momentary panic until we figured out it was PM, still the same day, so we went out and had dinner.
I could never do strenuous riding the same day, or even the next day.
