Fueling
Carbohydrate is the main fuel you burn when racing. Failing to fuel properly is a leading cause of underperformance in longer races.
Chipper kept things simple on race morning to avoid GI distress before the early start. He ate a light but carb-rich breakfast ~1 hour 15 minutes out from the race and then topped it off with a PF 30 Gel 15 minutes before the gun. This swimrun consisted of 13 swims and 14 runs, during which Chipper used two PF 30 Gels and a PF 90 Gel to average ~50g/h, below the carbohydrate recommendations for an event of this duration and intensity. Even though fueling can be a logistical challenge in a race like this where athletes change from swimming to running every few kilometres, Chipper should continue to train his gut and practice this strategy to be able to both tolerate more carbs and find easier ways to carry them, such as in his wetsuit pocket or picked up from aid stations to increase his intake towards ~60g/h to help maintain his energy levels until the very end.
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.
Whilst Chipper’s losses are on the moderate side, getting his hydration strategy right is still crucial when it’s hot and/or humid as his higher sweat rate in these conditions can result in significant net losses over the duration of a race.

Although this will have aided his hydration going into the event, to maximise the fluid retention benefits of preloading he should switch to the PH 1500. During the race, Chipper primarily relied on plain water from the 6 aid stations. He drank to thirst, slowing down through the aid stations to make sure he could take as much water as he needed. Chipper’s fluid intake will have likely replaced a good proportion of his sweat losses but, as a salty sweater, we would encourage him to include more sodium into his hydration strategy. Electrolyte Capsules may be the best fit for swimruns since these are easy to carry and pair with plain water picked up on course. While Chipper did not experience symptoms of dehydration during this event, increasing his intake will be especially important going into the longer ÖTILLÖ World Championships later this year.
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.
Chipper is a habitual coffee drinker and therefore has a high caffeine tolerance. For events under ~4 hours, the guidelines are to focus on precaffeinating with a dose of 3-6mg/kg. Chipper maintained his morning ritual by having a coffee with breakfast but to get closer to the recommended range in future, he could replace his pre-race PF 30 Gel with a PF 30 Caffeine Gel, to maximise the ergogenic effects he gets from 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.
