Istria 100 2025 Results

Istria 100 by UTMB happened last weekend. A fairly international field of runners found themselves in Croatia kicking off their trail running season. I was curious if the addition of events like Chianti and a few other spring events in Europe resulted in a dip in participation for this event, but Istria had about a 10% increase in starters in 2025 compared to last year.
