Chris' 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 felt fed the whole time across the race, with no flavour fatigue. I ate up until about 2 miles from the finish and I never struggled to eat during. I know I could've definitely handled more carbs throughout if I needed to but I didn't want to overdo it, so I just did what felt natural."
Our thoughts

Chris’s high carb intake across this gruelling race proves that his gut training efforts worked, as he comfortably tolerated the high volume of fuel to maintain his performance. His simple and consistent intake of PF&H products helped him to focus on the race whilst sticking to a robust fueling strategy. Chris traditionally enjoys a light breakfast before his big races and historically hasn’t consumed anything in the last 30 mins prior to the start. In future races, it could be beneficial for him to add a PF 30 Chew or PF 30 Gel to spike his blood glucose levels at the start line and delay the use of stored glycogen for later in the race. The on-course support Chris received from his crew at aid stations allowed him to carry only what he required for each section (up to ~10 miles at most) and regularly topped up with fuel. He opted for PF 300 Flow Gel in Flow Flasks as the main source of his carb intake because he’s found this the easiest to take on whilst running at a high intensity.

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.

Chris has been Sweat Tested to dial in his 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.

Whilst Chris’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.

"My hydration felt really good - I peed 5 times I think during the race. I did have a few cramps, but they were easy to manage and mostly went away after taking some electrolytes."
Our thoughts

Since temperatures ranged from 7 - 36ºC (44 - 97ºF), it was crucial that Chris's fluid intake was flexible enough to adapt to the varying conditions during the course of the day, particularly when his intake needed to be higher during the hotter parts of the day. The crewed aid stations provided frequent access to aggressive cooling strategies which involved water dowsing and ice bandanas, helping lower Chris’s core body temperature and prevent overheating. He also decoupled the majority of his carb, electrolyte and fluid intake across the day by supplementing the water he took on board with Electrolyte Capsules. By doing so, Chris could match both his fluid and sweat sodium losses, without affecting his carb intake, and maintain independent control over each of the three levers in the changing environment.

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

Chris has typically avoided caffeine during races, but has been working with PF&H Sports Scientist Tash, to introduce some during training to increase his perceived energy levels strategically at certain times where he would benefit most from the ergogenic effects of the stimulant. As a result, Chris used more caffeine than he has in any past races, supporting his performance to produce a great result. His caffeine intake came through a combination of PF 30 Caffeine Gels and energy drinks which ensured a steady trickle of the stimulant into his bloodstream.

Final thoughts

Chris' Satisfaction Rating

/10
I’m super happy with the time I ran, in other years with this time I would have podiumed or gotten way higher on the list, but it was insane to run that fast and still get 10th. I am really happy with it, the only issue was my quads feeling blown.
Chris
Chris put together a great race at Western States and was thrilled that his fueling and hydration strategy supported his performance to see him cross the finish line amongst the high calibre athletes. It was a pleasure for the PF&H Team to witness his performance first hand and crew him on-course to help meet his needs.

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.
