As part of the Podium Racing team competing in the supertri series, Kenji Nener is currently one of the top contenders in fifth place. The Nix Hydration Biosensor was spotted on him during his recent Chicago race and provided him with. valuable hydration insights on race day. Read on to learn more about the race and Nener’s sweat and electrolyte losses from that day.
What is supertri
Supertri – formerly known as Super League Triathlon – is a unique and innovative sprint-distance triathlon with spectator-friendly closed-course racing. The supertri Chicago included three continuous rounds of full intensity swim-bike-run. During the Chicago supertri event on August 25, 2024, Nener wore his Nix Hydration Biosensor. Please note, the Hydration Biosensor is not yet, currently approved for full water submersion. We’ve been actively testing the device. For the time being we recommend triathletes applying it during T1.

Race Day Conditions and Results
At the start of the Chicago 2024 supertri race, the Nix Index was 91, indicating extreme weather conditions. With a temperature of 88 degrees Fahrenheit and a solar load of 80%, hydration intel was critical. Data from Nener’s performance revealed heavy fluid and electrolyte losses across the board. Using the workout export function in Nix Solo, the data was parsed into key moments during race day.
Race Day Data:
- 53 minutes of active racing time
- 48.8 oz fluid lost, equating to an average of 55.5 oz per hour
- 1,198 mg of total electrolytes lost; 567 mg of sodium alone
- During his cool down, Kenji lost an additional 8.7 oz of fluid
Zeroing in on race time and cool down alone, Nener lost approximately 3.6 lbs of fluid translating into approximately 2.4% of his body mass, which is within the range of critical dehydration levels. Nener’s fluid losses place him in the 99% percentile of Nix users and the 65% percentile based on his electrolyte losses. Thankfully, his team utilized the real-time data during race day to ensure that he was adequately hydrating along the way.
Coached by Tim Don, renowned British triathlete and endurance athlete, Nener is utilizing the data collected from his Nix Hydration Biosensor to dial in his hydration strategies for the next supertri as he continues his efforts to sit atop this season’s podium.
