After tackling the Triple Mix the athletes face their toughest challenge yet: to race three stages of super-sprint triathlon on heavy legs, exhausted lungs, and overclocked hearts - in the pouring rain lashing Jersey.
The Eliminator format comprises three stages of swim-bike-run with a break between each stage. The break commences when the winner of the preceding stage crosses the finish line. This means every athlete behind the stage winner has even less time to recover.
Only the top 15 finishers from Stage 1 will proceed to Stage 2, while only the top 10 finishers from Stage 2 can contend for the win in Stage 3.
For every stage, the competitors will swim 300 meters, cycle six kilometers, and run two kilometers. Only the fastest will survive.
This format rewards athletes who can manage their energy output and balance this with how much they will benefit from getting more rest after each stage.
As the two previous days of racing have shown, the winner is often determined in the final moments.
