4-16-4 Aarhus Bay Triathlon 2026

The Aarhus Bay Triathlon 4-16-4 is an annual event held at Tangkrogen in Aarhus. Its short format consists of a 400-meter swim, a 16-kilometer bike ride, and a 4-kilometer run. This is a non-draft race, meaning cyclists must maintain their own space on the course and cannot ride in a pack. The event welcomes participants of all ages, skill levels, and experience, making it suitable for both newcomers and seasoned triathletes. The race routes are entirely closed to traffic, a significant feature for a compact triathlon course, contributing to its reputation as one of Denmark's safest events. The broader Aarhus Bay Triathlon program features a children's triathlon, recreational races, and championship events for youth and elite competitors. Upon finishing, participants are awarded a medal and refreshments, complemented by a communal atmosphere and spectator support at the venue. The race was revived in recent years and is now a consistent Aarhus tradition, emphasizing straightforward and secure competition.
