Thanks. Around here, we usually calculate up to 400 m of vertical climb per hour for experienced mountaineers walking, anything beyond that is quite ambitious. I used to run track in high school, so my best in the flat 1000m is 2:45 min. Of course, I then ended up putting on around 10 kg of muscle for wrestling in college, which I have to carry when running. But I just did this for fun, and only ran it once. If I had been up there longer, I would have tried to push my time under 4 min, because I used to have a rule of thumb never to run a kilometer in training slower than that... but the terrain was a bit difficult for that, a short stretch of it was ferrata (which is what we call mountain paths where they put metal cables into the wall to secure safety harnesses to, and/or install steps made by iron bars), not sure if I would have managed. But my one advantage was that by walking that path 60 times or so in the previous 3 weeks, I knew the place of every single rock.
