Race guide

Swim, bike and run preparation

The current event overview classifies the swim as ocean, the bike as rolling and the run as rolling. Use controlled effort over repeated rises on the bike, then rehearse a short, easy run after similar riding. 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.
