Travelling around the Balkans loosely following TET route in summer 2021. Bosnia & Herzegovina. I was following the TET very closely in Bosnia. It has everything, fast, slow, technical section, open sections, forest sections, rocks, gravel and very little of pavement. Everything is mixed in great proportions and there is never a feeling of too much of one kind of riding. It was an absolute blast!
