Amelia'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.

"I was able to finish with strong legs at the end. Caffeine gels for the win!"
Our thoughts

Even though Amelia had a hectic few days leading up to Gravel Wales, she still managed to ensure she started the race off with full glycogen stores by sneaking in some extra carbohydrates with a carb-rich dinner the night before and breakfast the morning of. Her dedication to fueling continued once starting the race, as she used PF Carb Only Drink Mix, PF 30 Gels and PF 30 Caffeine Gels to hit well over the recommended 90g/h. Since she’s been practising it in training and her other races, she knows her stomach can comfortably handle this dose of carbs. It paid off in a stellar performance where her energy levels were high the entire time, from the start right up until the finish line.

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.

Amelia has been Sweat Tested to dial in her hydration plan

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 Amelia’s losses are Very High (1,617mg/L), nailing her hydration strategy remains important, even when it’s Mild.

"I didn’t have any cramping issues other than some stomach cramps two hours in but those passed."
Our thoughts

Amelia is a pretty salty sweater who’s suffered from bouts of cramping in races previously, but since incorporating more sodium into her strategy, she’s had significant improvements. She added PH 1500 to her bottles of PF Carb Only Drink Mix so every time she drank fluid, she knew she was supporting her electrolyte needs. Considering the mild conditions and four-hour duration of this race, her sweat rate was likely low enough that, even though her relative sodium concentration was lower than her personal losses, it didn’t accumulate enough to negatively affect her performance. The minor stomach cramps this time may have been from consuming different foods to what she is accustomed to in the lead up to the race, compared to a specific electrolyte imbalance. In the future, it’d be worth dialling up the sodium to be more in line with her salty sweat losses to ensure she avoids cramp and can retain the fluid she’s consuming. Practically, since she put a single 500ml (16oz) serving of PH 1500 in larger bottles (750ml / 24oz), thus diluting down the concentration, she could add another half tablet to each, or carry Electrolyte Capsules to better hit her target.

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

Incorporating a pre-race PF 30 Caffeine Gel has been a helpful strategy for Amelia, giving her an essential energy boost as she sets out on course. She also used two more doses later on, which she credits for keeping her legs strong towards the latter part of the race. Caffeine can help mask fatigue and reduce perception of effort, and since her intake fell within the recommended dosing range of 3-6mg/kg of body weight, it certainly would have played a positive role in her silver-medal performance.

I am really pleased to pull off a 2nd place at the UCI Wales gravel event. Preparation for this race wasn’t perfect, but it definitely helped to have a plan, guided by Lexi at PF&H, and to keep ticking as many of those boxes as possible.
Amelia
Amelia had an incredible race and showed off the hard work she’s been putting into her training, as well as her consistent fuel and hydration practice. Her race nutrition plan has been fine-tuned over this season and her execution of it on the day clearly supported her performance. Adjusting her bottle composition to increase the sodium concentration will be the final tweak going into the championship race, but she should be confident in her fueling abilities to power her through to the finish.

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.
