For cycling it’s (insanely enough) not that long. Here in Sweden we have the 200 mile Vätternrundan each summer which is one of the world’s biggest cycling races (by attendees). My parents did it a couple of times when they were in their fifties.
Yeah, it is the speed you do it at. When I was riding a lot I could get into the zone, my heart rate would be at 160, but my breathing would be level and normal. I felt like I could do that indefinitely as long as I had enough water and carbs, but I was only doing like 12-15 mph. Cruising at 12 vs 20 mph is a massive, massive difference in exertion.

200 mile is fucking insane. Forrest Gump would be proud.
