Istria300 2027.
Road · Poreč, Istrien · Croatia
2 Oct 2027
Istria300 starts and finishes in Poreč on Istria's west coast and sends the field inland, where the loop links the hill towns of the peninsula. Its signature feature is that riders choose the long, middle or short course at the splits out on the road rather than at sign-up. Everyone starts and finishes together in the coastal town itself.
