James' strategy

Fueling

Carbohydrate is the main fuel you burn when racing. Failing to fuel properly is a leading cause of underperformance in longer races.

James' Energy Rating

"I planned out exactly what I wanted to consume for each hour of the race, but when it came to it, I really struggled to stick to the plan and my energy levels dropped because of it."
Our thoughts

Our Athlete Support Specialist, James ‘Ricky’ Hatton used a fueling strategy that he’s fine-tuned to his needs and used at some of his previous races. He set off a little faster than anticipated but with his strategy written out for his crew (the PF&H Sport Science Team to follow, he was able to mostly stick to this plan for the first couple of hours. However, due to the increased pace and the humid conditions, Ricky’s fueling tapered off as the race went on and ultimately fell significantly below the recommended carbohydrate intake for a race of this distance and intensity. As a result, his energy levels faded, but fortunately, the team provided a morale boost and pacing support to ensure he reached the six-hour finish point. Ricky can focus a little more on training his gut during higher intensity and warmer sessions so that his carb intake is sufficient to support his performance for the duration of the run no matter the conditions.

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.

James 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 James’s losses are on the moderate side, getting his hydration strategy right is still important if he wants to perform at his best.

"I tried to keep my fluid intake up throughout, especially considering how hot and humid it felt whilst running around the track."
Our thoughts

Ricky is well-known in the office for his daily energy drink, and this race was no exception. His fluid intake consisted of water, energy drink and PF Carb Only Drink Mix, which he supplemented with PH Electrolyte Capsules. With the sun beating down on the 400m outdoor track, Ricky’s sweat rate was higher than expected, and he struggled to maintain a high enough fluid intake to prevent dehydration. Despite his efforts, his fluid and electrolyte intakes were below the recommended guidelines and as a result, his sweat losses far exceeded his replacements. With accurate pre and post weigh-ins from the Sports Science Team on the ground, Ricky’s measurements revealed he finished 4.7% lighter than he began, so it’s safe to say he was severely dehydrated! A more proactive sodium strategy may have helped in order to more closely match his sweat sodium losses as well as increase his drive to drink in the early stages. He could add some PH 1000 to his PF Carb Only Drink Mix or swap it for some PF Carb & Electrolyte Drink Mix.

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

Ricky’s caffeine intake was within the scientific recommendations to help him reap the ergogenic benefits of the stimulant, lowering his perception of effort and ideally delaying fatigue. He used PF 30 Caffeine Gels and took sips of energy drink across the race from his Soft Flasks, although he could have benefited from a couple additional PF 30 Caffeine Gels to boost his energy in the latter stages.

Final thoughts

James' Satisfaction Rating

/10
I am really pleased to have finished the race, but starting off at the pace I did really set me up for a big challenge, and I paid the price.
James
As always, it's a pleasure to crew one of our own PF&H Team Members at a race, especially being able to support Ricky every two minutes at the Ultra Loop Track Edition! Ricky found the constant pounding of one set of muscles really took its toll after several hours, and the change of direction every two hours flared up an old hip injury which further hampered his progress. It was such a taxing race, both mentally and physically, but he gained some extremely detailed sweat, fuel and hydration data, which he can use to inform his next 100km ultra in just two weeks’ time.

There is a high level of confidence in the accuracy in the data. The numbers presented are believed to be a very close reflection of reality. There may still be one or two estimations made in the data (an inescapable part of field data) but there is reason to believe that these are accurate and that possible error has been kept to a minimum. It is data that has been collected and recalled as accurately as is possible given the uncontrolled settings/circumstances.
