Florian'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.

Florian's Energy Rating

/10
"Energy was good. I just executed my plan and never had a feeling that I was low on energy."
Our thoughts

Florian followed his fueling plan to perfection, and since the lead group was faster than anticipated, he ended up consuming more than the ~118g/h he achieved at the World Champs last year and his 120g/h target. We’re seeing more and more elite level riders like Florian push higher than the recommended 90g of carb per hour, even over 120g/h, but this takes huge amounts of gut training. Florian and his teammates practise this year after year, and he even estimated pre-race he would have drunk over 500 bottles of PF Carb Only Drink Mix this season alone!

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.

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

"At the end I was a bit dehydrated, but I think that is normal for the last 30 to 60 minutes, I didn’t think about eating and drinking as much as I was just going for the win."
Our thoughts

Florian missed two of his bottle handoffs on the day, which can certainly happen even to the best during hard and fast racing. Thankfully, Florian had prepared for this with backup options, managing to pick up two individual bottles and two musettes during the race, each with two bottles, which enabled him to hit his pre-planned ~1L per hour fluid intake. This is an impressive intake over a race where drinking is logistically challenging, and even though the conditions were mild, the relative exercise intensity was extremely high, so Florian would still have been sweating a lot. In addition to gut training for fuel intake, Florian has also used this protocol to improve his fluid tolerance. With his low-moderate sweat sodium concentration, he has built an individualised replacement strategy of ~50% PF Carb & Electrolyte Drink Mix and ~50% PF Carb Only Drink Mix to closely match the concentration of his losses.

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

With only two PF 30 Caffeine Gels on race day in Belgium, Florian fell just short of the general recommendations. Making his final pre-race carb dose a Caffeine Gel and/or swapping out another one or two of his PF 30 Gels for additional PF 30 Caffeine Gels could maximise the ergogenic effects from the stimulant, as there is some evidence to show even a moderate dose (4-6mg/kg) to have a significant impact on performance in comparison to a smaller, 1-3mg/kg dose like Florian consumed here.

It was fast from the start, but I just stuck to the plan!
Florian
Florian defended his 2023 podium position at the UCI Gravel World Champs with an awesome performance powered by a well executed fuel and hydration strategy. His plan met the extremely high demands of the race whilst also meeting his individual requirements.

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).
