Tash'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.

Tash's Energy Rating

"My legs felt like they couldn’t really push on the bike, but I didn’t have any dips in energy. On the run my stomach felt weak, so I didn’t eat as much as I planned. There is still work to be done for next time."
Our thoughts

Tash meticulously planned and logged her carb-load the day before this race, consuming ~10g per kilogram (2.2lb) of bodyweight, which is right in line with the scientific recommendations. Inspired by Ant’s carb-loading email, she hit her target using a couple of bottles of Carb Only Drink Mix, a handful of sweets, white rice and copious amounts of porridge. During the race, Tash was on track to hit her planned carb numbers, before ejecting her bottle of PF 300 Flow Gel in the final 30 minutes of the bike. Unfortunately she developed a ‘stabbing pain’ in her stomach during the early parts of the run, so she couldn’t take in much fuel, and only had the mouthful of Flow Gel and a single PF 30 Gel instead of her planned ~75g/h. Tash admitted she hadn’t done as much gut training as she’d have liked before this early-season race, so going forward, will look to simulate her planned carb targets more often during race-specific training sessions.

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.

Tash 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.

Whilst Tash’s losses are on the low side, getting her hydration strategy right is still important if she wants to perform at her best.

"I finished the bike feeling quite thirsty, but my current bike set up only allowed me to carry one bottle of fluid. I will re-think this ahead of my next race, but this may have caused some of my stomach discomfort on the run."
Our thoughts

Tash has struggled with debilitating dehydration at several of her previous races, including headaches and drops in blood pressure. To combat this, she preloaded well beforehand, and planned to slightly ‘over-salt’ her drinks throughout to encourage her body to retain as much water in the blood as possible. Despite doing this, she reported feeling quite thirsty, likely a result of not having any plain water and coming in under her fluid target particularly on the bike. Her high-sodium Soft Flask with one PH 1500 (Tablet) in 250ml was part of the strategy to encourage her to drink during the run, which is something she typically struggles with; this strategy worked well, and as a result she drank more cups of water than she ever has from the run aid stations. Slightly reducing the relative sodium concentration in her plan could help combat her excessive thirst during and after the race, perhaps by adding a bottle of plain water to her bike set up.

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

Tash enjoys coffee as much as the next person in the office, so it was no surprise to see plenty of caffeine in her fuel and hydration strategy. After dropping her bottle of Flow Gel on the bike, Tash reached for the spare gel in her bento box to try and limit the damage, but accidentally had a PF 30 Caffeine Gel instead of a regular PF 30 Gel. Noticing this, she decided not to take the whole gel during the bike, as she still wanted to take a separate Caffeine Gel during the run, and understood the possible risk involved with going above and beyond the scientifically recommended caffeine dose. However, since she was experiencing stomach pain on the run, she ended up not taking the caffeinated gel, so her total intake was well within the recommended range for someone of her body weight.

Tash's Satisfaction Rating

This was my first race as part of the PF&H team, so I’m buzzing to take the win after battling an injury niggle for a few months. I’m not sure why my stomach felt so bad running, but I think I pulled a stomach muscle which really put me off eating. Some more gut training would definitely help, but my lack of bike-run specific training due to the injury could also have played a role.
Tash
Tash crushed her first race wearing the PF&H colours, and despite some pretty severe stomach pains during the run, still ran a solid even split for the 14 miles (22.5km). As this race had no aid stations on the bike course, Tash couldn’t drink as much as she’d have liked, but plans to add an extra bottle to her bike set up to alleviate this issue. Some more race-specific gut training will also ensure her body is primed for tolerating a higher fuel intake, and prevent any gastrointestinal distress when racing this hard.

There is good confidence in the accuracy of the data reported. An athlete feels that the numbers closely reflect what they consumed despite a couple of estimations which may carry some degree of error. The majority of what was consumed is recorded to a high level of specificity (most volumes are known through the use of bottles brands quantities flavours). The numbers are very plausible and align with previous data recordings (if an athlete has collected data previously).
