Well, this looks hard, but there IS a ferry transfer, maybe two of them, and I’m a sucker for a ferry.
Starting in Slovenia, riders get rolling views of castles, lakes, and forests. There is a painfully difficult hike-a-bike section as the course swings into Croatia. The climbs are all steep, the weather is unreliable, and the chances of getting lost seem better than you’d want them to, but eventually it all ends in the historic Italian city of Trieste.
I’m not signing up, but I am filing it away for later.
