“This is the Best marked course I’ve ever ran!”

100 Miles of Istria 2014 overall winner

I really like this race and especially the scenery. It’s a hard race, even for me :)
Francesca Canepa (ITA), 100 Miles of Istria 2015 female winner, 3rd overall
I cannot repeat enough how well organised, well crewed and well marked this race was. Small fluttering red flags scattered around the course almost every 30 meters guided us along paths through the various checkpoints and aid-stations filled with water, cookies, Nutella© bread, sandwiches, salty snacks, carbonised water, coke and even gluten free/dairy free products for the sensitive ones.
Peter Koraca (UK), 65 k competitor
The part of the course that I could see during the day was amazing! It was like running through the history.
