Running Blind: How Rob Weijens Conquered Rotterdam Marathon With a Guide by His Side

On a crisp April morning in Rotterdam, Rob Weijens laced up his running shoes not to chase a personal best, but to redefine what’s possible. Blind since childhood due to a genetic condition, Weijens crossed the finish line of the 2024 TCS Amsterdam Marathon — wait, no, correction: the 2024 NN Marathon Rotterdam — guided every step of the way by a sighted running buddy. His completion of the 26.2-mile course wasn’t just a personal triumph; it was a vivid reminder that endurance sports remain among the most accessible avenues for athletes with visual impairments.

The NN Marathon Rotterdam, one of the Netherlands’ premier road races and a World Athletics Gold Label event, drew over 18,000 participants on April 7, 2024. Among them was Weijens, a 34-year-old software developer from Haarlem, who has competed in blind running events for nearly a decade. Unlike sports such as badminton or football — where tracking a fast-moving object relies heavily on vision — running, especially with a guide, allows athletes like him to compete on near-equal footing. “You don’t need to spot the ball to feel the rhythm of your feet on the pavement,” he said in a pre-race interview with Atletiek.nl, the Royal Dutch Athletics Federation’s official platform. “You just need trust, communication, and someone willing to run beside you.”

The Guide System: More Than Just a Runner

In Paralympic and elite blind athletics, athletes in the T11 classification (total blindness) compete with a guide runner connected by a taut rope or band, typically less than 30 centimeters long, running shoulder-to-shoulder. The guide acts as the athlete’s eyes — calling out turns, elevation changes, surface hazards, and pace adjustments. For Weijens, who competes in the T12 category (severe visual impairment), the rules allow slightly more flexibility, but he still relies on verbal cues and physical proximity for safety and navigation, especially in crowded urban marathons.

His guide for Rotterdam was Martijn van der Meulen, a longtime training partner and member of the Haarlem Atletiek club. Van der Meulen, who has guided Weijens in multiple half-marathons and 10K races, underwent informal coordination drills in the weeks leading up to the race, practicing pace synchronization and communication protocols. “It’s not about pulling or pushing,” van der Meulen explained post-race. “It’s about matching stride, sharing breath, and becoming one unit for 42 kilometers.”

The duo maintained an average pace of 5:45 per kilometer — a strong showing for a non-elite recreational runner, especially under the added cognitive load of guiding. They crossed the finish line on the Coolsingel in 4 hours, 12 minutes, and 38 seconds, well within the race’s 6-hour cutoff. Official results from the NN Marathon Rotterdam 2024 results page confirm Weijens’ time and placement in the men’s 30–34 age group.

Why Running Works When Other Sports Don’t

As noted in the original Dutch-language report from Noordhollands Dagblad, sports requiring hand-eye coordination — like badminton, tennis, or football — present significant barriers for athletes with low or no vision. The speed, spin, and unpredictability of a shuttlecock or ball build real-time tracking nearly impossible without functional sight, even with adaptive equipment or auditory aids.

But endurance sports like running, swimming, and rowing rely more on proprioception, rhythm, and aerobic capacity — senses that remain intact regardless of visual input. In swimming, tappers (guides who use poles to signal lane ends) allow blind athletes to train and compete safely. In running, a guide or tether system provides spatial awareness. “It’s not about overcoming blindness,” said Lydia van der Zee, a sports psychologist specializing in disability sport at the University of Amsterdam. “It’s about designing environments where vision isn’t the prerequisite for participation.”

The International Paralympic Committee (IPC) recognizes athletics and swimming as two of the most accessible Paralympic sports, with events offered across all visual impairment classifications (T11–T13 for track, S11–S13 for swimming). World Para Athletics’ official guidelines emphasize that guide runners are not assistants but integral competitors — subject to the same anti-doping rules and eligible for medals in their own right when guiding medalists.

A Growing Movement in Adaptive Running

Weijens’ finish is part of a broader trend. In recent years, guide-running programs have expanded globally, from New York’s Achilles International to London’s See Sport Differently initiative. In the Netherlands, the Gehandicaptensport Nederland (GSN) foundation supports over 200 blind and partially sighted runners through club partnerships and guide recruitment drives.

At the 2023 World Para Athletics Championships in Paris, Dutch sprinter Joy Jeanne Bertrand, guided by Sam van der Schoot, won bronze in the women’s 100m T12. Meanwhile, in distance running, athletes like Belgium’s Marcella Naaijens (T11) have broken barriers in marathon events across Europe, often with rotating guide teams to manage the immense physical and mental demands of long-distance guiding.

Technology is similarly evolving. Experimental systems using GPS-based audio cues or haptic feedback vests are being tested, though none yet replace the nuanced, real-time judgment of a human guide. “Tech can help with straight lines,” said van der Meulen. “But in a city marathon — with crowds, detours, and sudden stops — you still need a person who can think, react, and communicate in the moment.”

What’s Next for Weijens and the Guide Running Community

Weijens says he’s already eyeing the 2025 edition of the NN Marathon Rotterdam, possibly aiming to break four hours with optimized pacing and guide rotation strategies. He also hopes to mentor newer athletes entering adaptive sports, emphasizing that the first step — literally and figuratively — is often the hardest.

“People assume you need to be ‘inspirational’ to run blind,” he said. “But I’m just a guy who likes running. The barrier isn’t my eyesight — it’s whether someone’s willing to run beside me. And luckily, in Rotterdam, there were plenty of people who were.”

As the global adaptive sports movement gains visibility — fueled by increased Paralympic coverage and grassroots inclusion efforts — stories like Weijens’ serve as both motivation and blueprint. They show that with minimal adaptation — a tether, a voice, a shared stride — the starting line is open to all.

The next confirmed checkpoint for the NN Marathon Rotterdam is the release of the 2025 race date and registration opening, expected in late summer 2024 according to the event’s organizing committee. For now, Weijens’ finish stands as a quiet but powerful affirmation: in the sport of running, vision may guide the eyes — but it doesn’t define the heart.
