Four athletes, one training ground, and the story behind

Earn Your Lane — Top4Running

Potchefstroom, South Africa — where preparation takes shape before the world is watching.

Every season has a starting point, and for many of Europe's top track and field athletes, it doesn't begin at a competition — it begins at a training camp.

For our newest Earn Your Lane campaign, that starting point was Potchefstroom, a well-established training destination located in the north-east of South Africa. Known for its altitude, warm climate and reliable conditions, it has become a go-to location for athletes and federations looking to prepare during the European winter.

The goal of the trip was clear: to document what preparation actually looks like. Not just key sessions, but the full rhythm of daily life — training, recovery, routine, and everything in between. Over several days, the team followed four athletes as they built towards the upcoming outdoor season and major championships, capturing moments that rarely make it into the spotlight.

Because before the races begin, there is always this phase — consistent, structured, and often unseen.

Following the work behind performance

Potchefstroom offers something that is difficult to replicate elsewhere during the winter months in Europe: stability. Athletes can train outdoors, maintain consistency, and focus purely on progression without interruption. The altitude adds an additional layer of physiological adaptation, while the predictable weather allows for high-quality sessions day after day.

But beyond the conditions, what stands out is the routine. Early mornings, repeated sessions, recovery blocks, gym work, and the discipline to stay consistent across it all. This is the environment where performance is built — not in single moments, but in accumulation.

Four athletes. Four disciplines. One shared phase

To capture this reality, we followed four athletes at different stages of their careers, across different disciplines, but all connected by the same objective: preparation. A sprinter, a middle-distance runner, and two combined-events athletes — each bringing a different rhythm to training, a different kind of pressure, and a different story.

What connects them is not just performance level, but timing. All four are entering a crucial phase of the season, building towards the outdoor calendar and major championships. Potchefstroom becomes their shared ground — a place where their individual journeys overlap, even if their events, goals and paths differ.

Ida Karstoft — experience, precision, consistency

Danish sprinter Ida Karstoft represents Sparta Atletik & Løb and is one of the leading figures in European sprinting. A two-time Olympian (Tokyo 2021, Paris 2024) and European Championships bronze medallist, she has built her career through consistency at the highest level. She is also a national record holder across five events, including the 200 metres.

In Potchefstroom, her approach reflects that experience. Her sessions are precise, controlled and highly structured, with a clear focus on execution. There is no excess, no unnecessary variation — just repetition at a high level. For an athlete who competes in races decided by fractions of a second, that level of detail is what makes the difference.

Smilla Kolbe — stepping into the next level

German middle-distance runner Smilla Kolbe, competing for Eintracht Frankfurt e.V., arrives in a different phase of her career. Over the past year, she has transitioned into the national elite, breaking the two-minute barrier in the 800 metres, winning her first national title, and making her debut at the World Athletics Championships.

That progression is visible in her training. Sessions are no longer just about development, but about refinement and consistency at a higher level. Middle-distance running requires a careful balance between speed and endurance, and her preparation reflects that — combining intensity with control, and building the ability to respond to the demands of competitive racing.

The upcoming season brings a clear objective: defend her national title and establish herself internationally.

Sven Roosen — rebuilding towards the top

For Dutch decathlete Sven Roosen, preparation carries a different narrative. After achieving podium finishes at the European U23 Championships (bronze in 2021, silver in 2023) and finishing fourth at the Olympic Games in Paris 2024, he has established himself among the top decathletes globally.

However, a longer injury break has shifted the focus of this phase. Training in Potchefstroom is not just about performance, but about rebuilding — strength, movement, and confidence across all ten disciplines. The decathlon demands completeness, and that means every element must be restored with precision.

His planned return in Götzis marks an important milestone, with the European Championships in Birmingham as a key target later in the season.

Sophie Weissenberg — the process of coming back

German heptathlete Sophie Weissenberg, representing TSV Bayer 04 Leverkusen, brings both achievement and resilience into this training phase. After winning silver at the European U23 Championships in 2019 and placing seventh at the World Championships in Budapest 2023, she had qualified for the Olympic Games in Paris 2024.

A torn Achilles tendon during warm-up ultimately prevented her from competing.

Potchefstroom now represents the beginning of her return. Her training is focused, measured and deliberate, with an emphasis on rebuilding trust in her body while gradually increasing intensity. Combined events require both physical and mental stability, and her preparation reflects that balance.

Her comeback is set for Götzis — a stage that will mark not just a return to competition, but a continuation of her development at the highest level.

Where the lane is earned

The Earn Your Lane campaign is built on a simple idea: performance is not defined by competition alone, but by everything that leads up to it.

By documenting athletes in an environment like Potchefstroom, we believe to highlight the reality behind elite sport — the consistency, the structure, and the effort that often remains invisible. It is about showing the process, not just the result.

Because when the season begins, and the athletes step onto the track, what we see is only the outcome.

The work has already been done.

The lane is never given.
It is earned — long before the race begins.
