Jen'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

Jen's Energy Rating

"My energy was really good in general, but dipped a bit towards the end of day 2. I was prepared for it to be miserable on day 3 because I have never run more than a marathon so it was unknown territory, but I felt so good! I had no specific dips in energy, other than mentally, and wouldn’t have changed anything in terms of fueling. "
Our thoughts

Jen has a lot of experience in racing long distance triathlons, so this ultra-distance event felt somewhat familiar to her. She used her simple, tried and tested strategy to effectively fuel across the three days so she could mentally focus on her performance. Fortunately, she had a crew supporting her throughout the event, passing her ‘fuel bottles’ wherever needed. Across the three days, Jen averaged over 90 grams of carbohydrate per hour; ~104, ~111 and ~92g/h for each day, respectively. With such a demanding event, it was imperative that she fueled consistently to maintain her energy levels and prevent any dips in performance in the latter days. She relied solely on Carb & Electrolyte Drink Mix and Carb Only Drink Mix for the swim and both bike sections of the event, followed by a mixture of PF 30 Gels, PF 30 Caffeine Gels and some energy drink during the run section. The variety in products helped stave off flavour fatigue and the years of gut training enabled her to comfortably tolerate high volumes of carb. And this event showcased those years of practice, with a total intake of over 2 kilograms of carbohydrate across the weekend!

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.

"Everything was perfect; I definitely wouldn’t have been able to take on anymore but it felt just right. I had a tiny bit of cramping running downhill towards the end of day 3, but that was more likely to be fatigue than hydration. I also had some abdominal cramping when running but took a couple of sodium pills and it disappeared."
Our thoughts

Similar to her fueling strategy, Jen has dialled in her hydration and knows what suits her needs best. She set herself reminders to drink every 20 minutes on the bike and pre-loaded before and after each day with either over-concentrated Carb & Electrolyte Drink Mix or PH 1500, achieving the ideal relative sodium concentration for replacing as much of her accumulated sweat losses as possible to maximise her hydration status and start as hydrated as possible the next morning. With multi-day events, it's important to drink frequently to prevent building up too large a deficit of fluid and sodium losses and with a high sweat rate, Jen made sure to nail her plan of ~1L/h across the three days. She had a couple of over-concentrated ‘fuel’ bottles that also contained high strength electrolytes and picked up extra bottles of plain water from her crew to dilute this. Additionally, by supplementing the plain water she consumed with Electrolyte Capsules on the run, she sufficiently replaced her sweat sodium losses in the latter stages.

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

Jen frequently uses caffeine in her day-to-day life, as well as in training and races, so she knows she tolerates the stimulant well. Her calculated caffeine intake reflects her total dose across the three days and was significantly higher than the recommendations of 3-6mg/kg. She relied on quite a high dose of the stimulant on day 3, where after two strenuous days, her energy levels were understandably wavering and she felt the effects of fatigue. The caffeine she consumed will have helped boost her perceived energy levels and slightly reduced her perception of effort.

If I could rate this 20/10 I would! I only had one mishap across the three days when I hit a pothole on the bike and lost all my mechanical kit and a bottle cage, but luckily my crew weren’t far behind and we could sort it quickly. I can’t believe I broke a new Ultraman women’s record by 1 hour and 9 minutes. To lead a three day race wire to wire was such an amazing experience and one that will likely never happen again. I executed the race as I had hoped and with the crew's help was able to stay on top of my nutrition and hydration plan really well.

It is fantastic to see Jen pull off such an incredible result with a new world record and genuinely have a great experience during such a mentally and physically demanding race. Her structured fuel and hydration strategy and seamless execution of it supported her efforts and energy levels across the race to ensure she tackled each day with strength. We are excited to see her smash her next race… and the next Ultraman!

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.
