This is the story behind REJOY—and why Sebastian Sanchez's worst year produced one of the most thoughtfully formulated hydration products in endurance sports.
Sometimes the best innovations come from the worst moments. REJOY's story proves that theory—and it starts with a crash that could have ended everything.
When It All Goes Wrong
Sebastian Sanchez was grinding through another disappointing season. Seven years of subpar results, two DNFs from fueling and hydration disasters—the triathlete's life wasn't exactly going to plan.
Then 2018 happened.
Training ride. Crash. Broken vertebrae in his neck. A bone fragment sitting less than 1 mm from his spinal cord—the difference between walking away and never walking again.
Sebastian walked out with a neck brace and enough painkillers to stock a pharmacy. Five weeks later, something felt off. He pushed for a full-body scan.
The news? Four more broken vertebrae. Seven broken ribs. The crash had destroyed him, and he didn't even know it.
The Long Way Back
Most people would call it. Sebastian doubled down.
First mission: ditch the painkillers. He went full natural, addressing pain through holistic methods instead of pharmaceutical shortcuts. As training resumed, this approach expanded to everything—performance, recovery, nutrition.
And hydration.
Years of trial and error. Natural ingredients only. Separating hydration from fueling. Testing electrolyte ratios until the formula was dialed.
The payoff? Exactly one year from the IRONMAN race he was training for when he crashed, Sebastian lined up at the 2019 IRONMAN 70.3 World Championship in Nice.
That comeback became REJOY.
Why REJOY Is Different
Sebastian's crash taught him that your body's foundation matters more than shortcuts. REJOY reflects that philosophy:
Balanced electrolyte concentrations: Precise sodium, magnesium, potassium, chloride, calcium, and phosphorus ratios validated through global sweat analysis
Natural flavors: Ginger lemonade, tangerine, and mixed berries—zero artificial anything, zero added sugars
Hydration-first approach: Only 1 gram of carbs per sachet because hydration and fueling serve different purposes
Daily-use friendly: Low calories and sugar mean you can use it beyond training for overall wellness
Another beauty? You control the concentration—more water on lighter days, less when you're pouring sweat. The 750ml baseline gives you the flexibility to adjust.
Summer's On The Way
Temperatures are climbing. Miles are stacking. Your hydration game needs to be locked in.
REJOY isn't just another hydration mix—it's proof that sometimes you must break completely before building something better.
Sebastian went from nearly paralyzed to the World Championships in 365 days. His hydration formula can handle whatever your summer throws at you.
P.S. When you’re 1mm from losing everything, you learn what really matters. For Sebastian, it was doing things the right way—naturally, scientifically, without compromise. That’s REJOY
