I do that on flat grounds with a roadbike, and can hold that for about 5 minutes, then falling back to about 60 to 65 kph, which I can hold for an hour, after which I usually am where I wanted to be. Rarely doing longer rides anymore. Usually at sea level.

That thing where you are 'running out of hill fast' I'm doing comfortably with 80 to 85 kph, and sometimes when in a 'real crazy' mood, and weather is allowing it (strong gusty winds, and possibility of black ice NOT good) with 90 to 95 kph. Though I'm really having to pedal like mad then, like in 1st gear, even faster.

Usually anywhere between 2000 to 4300m above sea level.

Got myself 2 really nice roadbikes recently, after having ridden an antique citybike with only 3 gears for almost 2 decades now.

It's like I'm young again! Unbelievable! :-)

If you’re suggesting doing 60 to 65 kph for an hour on a normal road bike after 5 minutes of 75 kph, I simply don’t believe you.

The world record 1 hour time on ultra flat indoor terrain set in 2014 was 51.852 km (32.219 mi). It’s climbed since then but your suggestion of ~63 kph for a full hour on a roadbike comes off as silly unless your using serious electric assistance.

I believe that you don't believe me, because that's what I always got. Except when on rare ocasssions ppl followed me with a car or motorbike. OR I pushed them to ride like they couldn't believe when they rode with me, which was also rare.

Can't do anything about it. Shrug. :-)
