Race guide

Swim, bike and run preparation

The current event overview classifies the swim as bay, the bike as flat and the run as flat. Practise a sustainable bike effort for prolonged flat sections, including handling and fueling in the position you intend to race. A flat run profile still needs conservative pacing after the bike. These classifications do not confirm the final map, water conditions, wetsuit decision or aid layout. Use this event’s athlete guide for those details.
