THE BALKAN RUNNING CALENDAR · FOR UK RUNNERS

FIND YOUR NEXT BALKAN RACE.

Filter road, trail and mountain races across the Balkans by date, country, distance and terrain — with one honest downside on every card. I am Serbian, I live in England, and I have watched British friends treat the London ballot as the only door into the sport. It is not.

This is a curated Balkan and Southeast European race calendar, not an exhaustive geographical definition or a complete list of every event — it grows as I check more races. Figures checked July 2026; always confirm dates and fees on the official race site before booking.
