Frequently Asked Questions
Q: Should I use Electrolytes like ISO MIX for HYROX, or are gels enough?
Gels are the simplest “quick hit” of carbs. KMC ISO MIX is useful when you want carbs + electrolytes in one bottle, especially in warm indoor venues or if you sweat heavily.
Many athletes use ISO MIX in training and then keep a gel pre-race for a simple race-day plan.
