That video ^^^ A seriously spectacular locale and some impressive riding – they’ve got bigger balls than me, that’s for sure.
However, this kind of wide-angle footage always makes locations like that look even more spectacular than they already are, everything looks deeper, steeper and scarier than if you were actually there riding it or, in my case, mostly faffing about and mincing it.
I’ve ridden a fair few kalderimis in Greece and while they might have lots of switchbacks and steps (and holes to catch unwary front wheels, as I know to my cost) most don’t have anywhere near that exposure nor are they as long.
As I said, a lot more balls and skill than I ever had….
