Swim, bike and run preparation
The current event overview classifies the swim as bay, the bike as hilly and the run as hilly. Practise sustainable climbing and safe descending on the bike; a flat-road speed target will not describe the climbing sections. The run also has elevation changes: pace by effort and protect your ability to run the later hills. These classifications do not confirm the final map, water conditions, wetsuit decision or aid layout. Use this event’s athlete guide for those details.

Final official-source checklist
Within race week, reopen the official event page and confirm date, venue, start procedure, entry status, course, rules, equipment, cutoffs and emergency guidance. Keep the current athlete guide available offline if the organiser provides one.
