Jan'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.

"My breakfast was a bit late before the start (around 90 mins pre-race) so I felt a bit full, and then the first climb was full gas. But, I built into the race and despite losing a bottle of carbs early on I had enough nutrition with me to get through the race."
Our thoughts

In the demanding conditions of the Traka 200km gravel race, which is characterized by steep climbs, technical terrain, long flat sections, and a further climb to finish, Jan drew on his background as a former professional cyclist to implement an aggressive and well-practiced fueling strategy. Accustomed to high carbohydrate intake, he averaged ~108g of carbs per hour using a combination of PF 30 Chews, PF 30 Gels, and PF Carb Only Drink Mix. Although a late breakfast left him feeling slightly full at the start and an early full-gas climb added intensity, he settled into the race rhythm and adapted his fueling strategy well. Despite losing a bottle of PF Carb Only Drink Mix early on, his experience and preparation ensured he had enough nutrition with him to sustain performance throughout the race, underlining the value of both high carb availability and flexible in-race execution.

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.

Jan 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 Jan’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.

"I dropped a full bottle early on while descending so I got a bit dehydrated. But I filled my other bottle with water at the first aid station and managed to get back on track."
Our thoughts

In warm and increasingly hot conditions at the Traka, starting at around 15°C / 59℉ and rising to 26°C / 79℉ by the finish, hydration was a key factor in sustaining performance over varied terrain. Jan averaged just over 600ml of fluid per hour, at a relative sodium concentration of ~748mg/L, which closely matched his expected sodium losses through sweat. His hydration plan included starting with bottles that were heavily sodium-loaded with PH 1500 - roughly double his estimated losses - and collecting similarly concentrated drinks at a planned crew stop at 115km. This was balanced out by additional plain water at unassisted feed zones (~55km and ~162km) and bottles containing PF Carb Only Drink Mix, resulting in a net sodium intake well-aligned with his individual requirements. Although he dropped a full bottle early in the race during a descent, he adapted effectively by refilling with water at the first aid station and staying on track with his fluid intake through the remainder of the course. His ability to balance high and low sodium sources dynamically demonstrates both experience and a well-calibrated hydration strategy.

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

Jan’s caffeine intake during the race was notably below standard endurance performance guidelines, which recommend 3-6mg/kg of body weight. He consumed only a single PF 30 Caffeine Gel during the race, resulting in a total intake under the advised range. While this may have limited his access to caffeine’s proven benefits, such as reduced perceived effort, improved focus, and enhanced performance, it's an area with clear potential for optimisation. Incorporating a more structured caffeine strategy in future events could offer a valuable performance boost, particularly in the latter stages of long, demanding races like this.

Jan's Satisfaction Rating

Despite dropping a bottle and a couple of tumbles on course, I was pretty happy with my performance. It’s a testing event, but one that I very much enjoyed.
Jan
Jan delivered a strong performance, effectively managing a demanding course and rising temperatures. His fueling strategy was well-executed, with a high intake that supported consistent energy levels despite the early loss of a fuel bottle. Hydration, while briefly disrupted, was brought back on track through smart use of aid stations and a well-balanced mix of high- and low-sodium fluids, resulting in an average sodium concentration closely matched to his sweat losses. The primary area for improvement lies in Jan’s caffeine intake, which was well below recommended levels. Addressing this in future events could provide a meaningful boost in focus and endurance.

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.
