The course behind your race
Bring your own race to the biggest start line.
Chattanooga hosts the championship weekend in August 2027. The river, hills and downtown streets are familiar from the regular May event, but the Worlds swim, bike and run routes have not been confirmed as the same. Train for the distance, the competition and the decisions you can control while the final championship map takes shape.

Set an opening power ceiling you can sustain for 90 km. Championship excitement should not dictate effort before the actual roads and gradients are confirmed.
