Nope. We used to cycle to the mountains nearby then cycle back couple times a week after school and then at least once on the weekend. On road bikes we were averaging ~40km/h so it was only 3-4 hours total, maybe less if we were pushing it. Not to boast but I was super buff back then, leg muscles like steel lol.

I have a friend who does trips like these.

With the right roads and equipment it's not that bad, but you really have to be in shape for this.
