Beh Rajeckým rínkom is a short asphalt running event in Rajec, Slovakia, starting from SNP Square in the afternoon. It is held around International Children's Day, and the main race is 5 kilometers, with Maratón klub Rajec as the organizer.
The event is built strongly around children: younger runners have a 1.5 km race, and the age categories stretch from non-walking babies under one year old through children up to 15. That gives it a local festival feel as much as a road race, with families, school-age runners, and very young children sharing the same town-square setting. The race is already in its 35th edition, so it is not a one-off kids' fun run but a long-running Rajec tradition.
