291 – Taking on the World’s Longest Stairway

March 9, 2026 twodisableddudes

In this episode, Sean shares the bold details behind his upcoming climb of the Niesen Stairway in Switzerland—the world’s longest staircase with 11,674 steps, the equivalent of climbing the steps of the world’s tallest building nearly four times. 

Because the stairs are a private emergency access route alongside a mountain tram, Sean and his team will attempt the ascent overnight in the dark, navigating uneven steps, changing terrain, and high elevation. He talks about the intense logistics, safety planning, and 26-week training process preparing him to take on the challenge while living with Friedreich’s ataxia (FA). 

The climb is also a fundraiser for his nonprofit, De:terminence, with a goal of raising $50,000 to help people with disabilities pursue life-changing physical achievements. With a team of 11, supporters, careful strategy, and a powerful purpose, Sean is setting out to prove that disability doesn’t eliminate adventure—it redefines it.
