6 Days in the Dome 24 Hour

Considering the duration and high energy demands of the race, Don’s fueling strategy needed to be simple yet effective to maintain performance without requiring too much mental focus. Fortunately, he had a tried and tested strategy that was exactly this. Despite the hip injury causing him some discomfort at times, his high intake of PF 30 Gels and PF Carb & Electrolyte Drink Mix kept him well-fueled from start to finish. Don also interspersed a few real food items to avoid flavour fatigue over such a long duration and managed to maintain perfect stomach comfort whilst doing so.

Don stayed on top of his hydration by aiming to consume around 500ml of fluid every hour, which contained our PF Carb & Electrolyte Drink Mix, as well as bone broth and cola. Given the mild conditions, this intake would have helped maintain his blood plasma volume and prevent race-impacting levels of dehydration over the course of the event. To further dial in his hydration strategy, he could have a Sweat Test to understand his sweat sodium concentration and see if the high concentration of sodium he used, which subjectively worked well for him, was an accurate match for his personal losses.

Don’s caffeine intake was slightly higher than the scientific recommendations for a race of this duration and intensity, and was also more than he’s used in previous races. Despite this, with ultra-endurance races like this one, it is usually advantageous to supplement caffeine throughout to combat the natural circadian rhythm and continue racing through the night. Don’s use of PF 30 Caffeine Gels and caffeinated gum would have helped him reap the maximal ergogenic benefits whilst supporting his energy levels and fighting fatigue.
