Official event pageWhat this race demands
Twierdza Triathlon Kędzierzyn-Koźle requires sustained pacing across consecutive swimming, cycling, and running disciplines over an Olympic-distance 51.5 km course.
Multisport transition
The race demands immediate physiological adaptation and technical control as athletes transition from swimming in the Oder River directly onto the cycling course through historic Koźle.
Pacing control
Because the total distance spans 51.5 km across three disciplines without stated elevation, athletes must maintain steady aerobic output through the bike leg to preserve running form for the final park run in Kędzierzyn-Koźle.
