Race guide

Swim, bike and run preparation

The organizer’s previous-edition overview classifies the swim as ocean, the bike as hilly and the run as flat. Practise sustainable climbing and safe descending on the bike; a flat-road speed target will not describe the climbing sections. 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.
