That looks quite the climb.   

I do not understand the reason for the intermittant changes in 'speed'.
To my mind they spoil the video, it seem to me they are playing with the video simply for the sake of playing with it.
I suppose others will disagree.

Wow, that is quite the climb.  Despite that the views are astonishing.  

Jumping through each scene is disrupting for me but that climb has beautiful panorama views. Thanks for the share.

That is quite the climb. Nicely captured!
