Mozart 100

Jack had a well-thought-out fueling strategy for the Mozart 100km. He’s dedicated the past few months to gut training in order to increase his tolerance of high carbohydrate intakes. Working with his crew, Jack successfully tweaked his fueling strategy to include more carb even during the lower temperatures when he was drinking less fluid. By increasing his carb intake in the latter stages, he was able to manage his energy levels and ensure his body had sufficient energy to support his performance.

Jack used PF Carb & Electrolyte Drink Mix and PH 1500 to replace his sweat losses, manipulating the volume and concentration based on the temperatures and his efforts. Despite feeling as though he drank too much, Jack’s relative sodium concentration and fluid intake were within the recommendations for his losses and a race of this duration and intensity. He may have needed to pee slightly more than usual due to the cooler conditions this time out, but Jack could do some sweat rate testing to dial in his total fluid consumption to ensure he is matching his intake to his losses as closely as possible.

Jack was slightly over the scientific caffeine recommendations, but would still have reaped the ergogenic benefits of the stimulant. Subjectively, Jack reported having no adverse side effects with this slightly higher intake of caffeine, although his increased need to pee may have been partially impacted by the diuretic nature of caffeine. He could try swapping one of his PF 30 Caffeine Gels for a regular gel in future races in future races as the literature suggests no additional benefit of this higher intake and instead increased risk. of negative side effects.
