Istrian inland trails and technical karst terrain, from Buzet to the Adriatic coast
Other trail races within 139 miles
The 110K starts in Buzet and spends its opening 20 kilometers on classic Istrian inland trails before merging with the 168K route. It's a deceptively demanding course — the rocky, technical terrain leading toward Buzet keeps the effort high despite more modest elevation numbers, and the coastal section near Umag brings welcome relief before the seafront finish.
