Electrolytes for HYROX training

Training for a HYROX event means running plus gym stations, often in a warm room. That means sweat. Here is a simple electrolyte routine for training and race day.

The short answer

For HYROX training, keep it simple: one scoop of Lula in a 500 ml to 750 ml bottle of cold water, sipped through a sweaty session, with plain water alongside. Or take your daily scoop after training in a big ice-cold glass. On race day, use only what you have tried in training. Lula has no caffeine and is not a pre-workout.

  • A HYROX event combines running with workout stations such as sled pushes, rowing and wall balls.
  • One scoop a day. Keep plain water to hand for double sessions.

Training

Around training sessions

HYROX training blends running with strength and conditioning, usually indoors. Warm gyms, little airflow and long efforts are a recipe for a lot of sweat. Sweat carries sodium out with the water, and how much varies a lot between people.

  • During a session: one scoop in a 500 ml to 750 ml bottle of cold water. Sip between stations and runs.
  • Double sessions or hot gyms: keep a second bottle of plain water. Lula is one scoop a day.
  • After training: one scoop in 750 ml to 1 litre of ice-cold water is another way to take your daily serve.

Race day

Race-day tips

  1. Nothing new on race day. Try Lula in training first, at the same strength you plan to use.
  2. Mix before you travel. A sealed, ice-cold bottle is easiest in a busy venue.
  3. Mind the caffeine elsewhere. Lula has none, so it will not add to any coffee or pre-workout you already use.
  4. Keep to one scoop. Drink plain water as well, to thirst.
