Pohodni, path super, long, road-like, only few kms on gravel, endurance. I have similar and harder ones already. For this feat I know what and how much you needed, congrats. I'm preparing a hard feat too (of course with MTB, which won't be published). As for mountain biking, roads don't count IMO, only gravel. Vršič counts if you go up gravel road

or Velka and many others.
Would like to see Jožax on MTB with me on a tour

And of course famous LG-ja
I like that he went with MTB, much more demanding than those with thin tires (road bikes) who drag along and think how much they've ridden.
