Greg'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.

Carb-loaded
?
T - 1-4hrs: Ate a carb rich meal (Low in fat & fibre)
pre-fueled

Greg's Energy Rating

"My energy actually improved as the day went on."
Our thoughts

Greg created a step-by-step plan in the weeks leading up to the race, and made further adjustments on the day to meet the extra fueling requirements of the higher race intensity than he expected. During this epic, old-school enduro race, logistics and fuel timing are as big a consideration as the quantity and type of carbohydrates. Greg began each of the three 38km / 24mile loops with a banana, then had 30g of carb in the form of either PF 30 Chews, a PF 30 Caffeine Gel or a PF 30 Gel during the climb to each stage. Clearly, this worked to keep his energy levels up and effectively fueled his high intensity timed stints each lap.

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.

"I felt good with my sodium levels but definitely could have taken on more water."
Our thoughts

Similarly to fueling, hydrating over an enduro race involves overcoming several logistical challenges. Greg had to carry all of his fluid each lap, as there were very few feed stations on course. He knew staying hydrated between stages was essential to maintain his performance over almost 15 hours of elapsed time. To manage this, he drank a 1.5L pack of PH 1500 and a 750ml bottle of PF Carb Only Drink Mix each lap. A Sweat Test would help Greg refine his sodium intake in the future, but without knowing his sweat sodium concentration, he implemented a proactive strategy and avoided any cramping. Greg felt he could have drank more water, but given the logistical challenges and added weight of more fluid he balanced his needs adequately, and peed twice during the race which supports this theory.

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.

Our thoughts

Greg consumed a PF 30 Caffeine Gel each loop to give an extra boost to his perceived energy levels. During the final loop he added an additional Caffeine Gel to ‘stay sharp’ as he felt his ‘brain was fading after 12 hours of racing’. This pushed him just above the general caffeine intake guidelines but given the long duration and nature of this race, plus Greg’s generally high tolerance for caffeine, it was appropriately timed to maximise the stimulant’s ergogenic effects.

Greg's Satisfaction Rating

The weekend was great. It was a pretty crazy race, and I crashed a few too many times but it went well from a nutrition perspective at least. Stoked to have raced, really happy with how the plan worked out and happy with my execution too.
Greg
As an experienced rider, Greg overcame the logistical nutrition challenges to grab a spot on the podium at his first attempt at this epic race. He implemented a thorough, well-timed fuel and hydration strategy that allowed for optimal high intensity performance when it mattered most during each stage, and kept him moving over the course of the whole day.

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.
