Fueling
Carbohydrate is the main fuel you burn when racing. Failing to fuel properly is a leading cause of underperformance in longer races.
Fenella managed to comfortably hit her approximate goal intake, falling in-line with the scientific recommendations of a race of this distance and intensity, whilst also experiencing no GI issues. As we often see in multi-sport endurance events, Fenella’s carb intake was front-loaded and dropped by over 50% across the disciplines, from ~113 g/h on the bike to ~57 g/h on the run. It could be beneficial for her to continue with some structured gut training in her training sessions at race intensity so she can increase her carb intake on the run whilst minimising the risk of 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.
Sweat sodium concentration (mg/L) is largely genetically determined and remains relatively stable. Knowing how salty your sweat is enables you to replace a good proportion of your sweat losses, which can range from 200-2,000mg/L.
Given Fenella’s losses are High (1,331mg/L), nailing her hydration strategy becomes especially crucial when it’s hot and/or humid.
Learn moreAlthough Fenella made a good effort across the duration of the race to replace her sweat losses as closely as possible, she was slightly under her goal sodium intake for someone with her sweat sodium concentration. In future races, it would be beneficial for Fenella to carry some Electrolyte Capsules on the run, or use PH 1500 in a greater proportion of her bottles to increase her sodium intake. On the surface, it’s likely that Fenella’s fluid intake was sufficient for a race of this distance in temperate conditions, but since she reported feeling thirsty, it may be sensible to increase this and rely on picking up a couple of extra bottles of fluid at the aid stations. To further dial in her fluid strategy, Fenella could do some sweat rate testing to more accurately match her sweat losses in races and navigate the possible risks and symptoms of dehydration.
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.
Fenella’s caffeine intake fell within the guidelines for a race of this distance and intensity and would have ensured she reaped some of the ergogenic benefits of the stimulant.

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.
