Hybrid Simulation Nutrition Kit: Contender

A HYROX simulation is a full or half-length practice run of the race format, done in training to test fitness, pacing, and strategy before race day. Fuelling it properly matters because your sim is the only real chance to test your race nutrition plan under true competition-length effort.

Each kit includes pre-portioned electrolytes, gels, and a recovery drink, along with clear nutrition instructions for when to fuel throughout your sim.

All three kits follow the same dietitian-curated fuelling approach; they differ in product brand and price point, so you can choose based on preference and budget.

Grip fatigues fast during sled pushes and farmer's carries. Liquid chalk is available as an add-on to any kit to help maintain grip through the earlier stations of your simulation. Under official HYROX rules, athletes can apply powdered or liquid chalk to their hands before the race begins, but carrying or using personal chalk during the race results in a 2-minute penalty. Many athletes use this pre-race window to apply liquid chalk as a longer-lasting grip aid for those first few stations, so it's worth practicing the timing in your simulation too.
