LEVELEN started in professional team sports, but has found a home with endurance athletes. Do you find yourself continually playing the trial-and-error game when it comes to your hydration and fueling? Do you ever suffer from debilitating muscle cramps during racing? When hydration and electrolyte replenishment can be the difference between a podium finish and a DNF, LEVELEN takes all the guesswork out and dials you into a specific hydration program. How much do you need to drink, how many grams of electrolytes you need, all determined by hydration sports science.

Take a LEVELEN #SweatTest and
take your ENDURANCE to the next LEVEL.


With endurance athletes, we’ve recorded sweat rates of 180mL to 4.80L per hour, and hourly sodium losses from 88 mg to 11,047 mg (a 100+ fold variance). That’s over five times the DAILY recommended intake, EACH HOUR. By maintaining proper fluid and electrolyte balance, endurance athletes can perform better, longer, and minimize heat-related illnesses like muscle cramps.

2016 Ironman World Championship Triathlete, Jana Richtrova, loses 1751 mg of sodium per hour. With a recommended daily allowance of only 1500-2300 mg of sodium per day, Jana can quickly become electrolyte depleted after an intense day of training or ten hours on the course.

Jana is a LEVEL 4 (SIGNIFICANT Electrolyte Loss). What LEVEL are you?
