Fueling
Carbohydrate is the main fuel you burn when racing. Failing to fuel properly is a leading cause of underperformance in longer races.
Mathias had a tough day out at IRONMAN® Frankfurt after a bike crash disrupted his race. This caused him to lose a bottle that contained a significant amount of PF 300 Flow Gel, so his energy levels on the bike began to plummet. He picked up some energy gels from the on-course aid stations in an attempt to replenish the lost fuel, but still struggled to hit his goal intake of 90 g/h. From his previous case studies, we know that Mathias is comfortable tolerating a higher carb intake of around 90g/h, so it’d be helpful to have a secondary source of carbs in case of future bottle losses to ensure he can still support his energy needs.
Hydration
Taking on board an appropriate amount of fluid and sodium is essential to maintaining blood volume and supporting the cardiovascular effort needed to perform on race day.
Whilst the absolute amount of sodium and fluid consumed per hour is important, it’s critical to consider these in relation to each other. This is known as 'relative sodium concentration' and it’s expressed in milligrams per litre (mg/L). How much sodium you’re taking in per litre of fluid is more important than the absolute amount taken in per hour.
Although Mathias drank some electrolytes ahead of the race, pre-loading with PH 1500, instead of with the lower concentration of PH 1000, could help him retain more water and prevent the need to urinate frequently. Despite this need to pee a few times on the bike, Mathias’ fluid intake was slightly lower than the recommendations for a race of this duration and intensity. It’s likely this was due to the high volume of his pre-race drinks and the increased nervous energy he experienced.
Caffeine
Beyond the Three Levers of Performance (carb, sodium and fluid), caffeine is one of only a few substances that is proven to improve performance for most endurance athletes as it can help stave off mental and physical fatigue.
Mathias started his race morning with a couple of coffees and a couple of energy drinks to get the stimulant into his bloodstream, and then strategically consumed a few PF 30 Caffeine Gels whilst on the run. By delaying his consumption of caffeine until later on in the race, he ensured he reaped the ergogenic benefits of the stimulant where he knew he’d need it most. This helped to reduce his fatigue slightly and boost his mental energy, contributing to the strong finish he was able to pull off.

Data Confidence?
There is an adequate level of accuracy in the data collected and the numbers reported. The athlete manages to recall what they ate and drank including most specifics (brands flavours quantities plausible estimations of volumes). However there are estimations made within the data which affect the overall confidence level in the data reported.
