Swim, bike and run preparation
The current event overview classifies the swim as lake, the bike as flat and the run as rolling. Practise a sustainable bike effort for prolonged flat sections, including handling and fueling in the position you intend to race. 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.
