Well, I'm an old man, in not such great shape. And I can go up five floors in less than a minute. If I'm tired, I just walk up, two steps per stride, with help using the hand rail. That's actually easier for me than going up one step per stride. And going down is harder on my knees.

Climbing five floors is qualitatively different from twenty. You can do the former anaerobically easily enough, but the latter is firmly in the aerobic regime unless you're an Olympic-level 400m sprinter.

Even an olympic sprinter will not be able to climb for 100m in anaerobic regime.

Sure. So you rest a minute or two.

But tell you what. I'll try the experiment later today.

The difference between five floors and twenty is roughly the same as the difference between a 10k and a marathon.
