How the day is laid out

The swim is held in a reservoir. The wetsuit call is made on race morning, against the temperature measured then.

The organiser publishes 3.8 km of swimming, 180 km on the bike and 42 km of running.

Everyone starts the swim together, in a mass start. The water is usually around 18 °C at this time of year.

The bike course is rolling, with about 2,250 m of climbing.

The run course is hilly, with about 2,700 m of climbing.

Typical temperatures for the month run from 7 to 17 °C.

The race was first held in 2016.

This is an extreme triathlon: the course is chosen for its terrain and its climbing, not for speed, and self-sufficiency and a support crew are part of the rules.
