William's strategy
Fueling
Carbohydrate is the main fuel you burn when racing. Failing to fuel properly is a leading cause of underperformance in longer races.
After spending some time chatting to Chris from the PF&H Sports Science team at a training camp earlier this year, William (‘Bill’) developed a straightforward fueling strategy to ensure he could focus on racing whilst meeting his energy demands. Most of his fuel came from PF 30 Gels, plus a few energy bars to avoid flavour fatigue by varying texture and taste. Given the intensity and duration of the race, and despite Bill’s consistent energy levels throughout, he could benefit from increasing his carb intake slightly to meet the recommendations. This would further bolster his energy, providing more available fuel to keep pushing harder. To do this, he should spend some time performing structured gut training across his training sessions to prevent any GI discomfort.
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.
Bill chose to use the PF&H on-course hydration provided at IRONMAN® Europe events, by picking up bottles of PH 1000 on the bike to replace his bottles of PH 1500 he had started with and consumed. Then on the run, he grabbed cups of PH 1000 from aid stations, enabling him to consistently replenish his sweat losses, and whilst we don't know Bill's sweat sodium concentration, he managed to prevent any performance-impacting levels of dehydration, so it's likely he replaced a good proportion of his losses.Considering the warm temperatures and his post-race symptoms, he’d likely benefit from increasing his fluid intake slightly to ensure he avoids any dips in performance.
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.
Other than the minimal amount of caffeine in coke, Bill didn’t take in any significant dose of caffeine during his race. In the future, it could be worth working out if caffeine is right for him to potentially implement in his races to reap the ergogenic benefits such as delaying fatigue and reducing his perception of effort.

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.
