Fenella'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.

Fenella's Energy Rating

"Despite my high spirits due to my love of this event, my legs just weren’t there on the bike."
Our thoughts

Throughout the race, Fenella relied on bottles containing PF 90 Gels and PF 30 Gels for the majority of her carb intake, whilst supplementing this with a couple of PF 30 Chews for a change in texture to avoid flavour fatigue. During the run, she stuck to her plan of taking one gel every 20 minutes, demonstrating the extensive gut training that Fenella does on a regular basis to increase her tolerance and reduce the risk of GI discomfort when racing.

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.

Fenella 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 Fenella’s losses are High (1,331mg/L), nailing her hydration strategy becomes especially crucial when it’s hot and/or humid.

"I’m really happy with how my new hydration strategy has improved the balance between my fluid and sodium losses."
Our thoughts

Fenella’s hydration strategy has evolved over the last few months after chatting to the team at PF&H, moving from primarily pre-mixed electrolyte drinks to a more water-based strategy supplemented with Electrolyte Capsules. This has helped her maintain her sodium balance whilst being able to adapt on-the-fly during races. In the run section of Challenge Roth, athletes are actually able to pick up their own supply of fuel and hydration from their support crew shortly after every aid station, eliminating the need to carry gels and bottles for long periods. Fenella’s partner and coach (Billy) handed her three Soft Flasks filled with PH 1500 at regular intervals throughout the marathon which helped her stay in line with her above average sweat sodium losses. To top up her electrolyte intake whilst drinking plain water on the run, Fenella also took Electrolyte Capsules.

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

After her usual pre-race coffee, Fenella sustained the caffeine levels in her system by consuming PF 30 Caffeine Gels consistently throughout both the bike and run legs. Although her consumption was above the general scientific recommendations, Fenella is well-adapted to having this quantity of caffeine and tolerates it well, reaping the ergogenic benefits that the stimulant can provide.

Final thoughts

Fenella's Satisfaction Rating
7
/10
Considering the low energy I had on the bike, I’m delighted with running my first sub-3-hour marathon.
Fenella
Even though Fenella suffered an illness just weeks before the event, she produced another great performance at Challenge Roth and the commentators once again drew attention to her relentless happiness on-course and genuine joy to be racing the iconic event. Her beautifully executed fuel and hydration strategy in the warm conditions, and against a stacked field, should give her confidence as part of her build towards the IRONMAN® World Championships in Hawaii later this year.

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.
