In this special episode of the Sapphire Running Zone Podcast, host Tim is joined by Clark Reynolds, also known as Mr. Dot, and his guide runner Alastair Ratcliffe, following Clark’s historic achievement at the Brighton Marathon.
Clark became the first blind person to complete a marathon using smart glasses linked to the Be My Eyes app, allowing sighted volunteers from around the world to guide him in real time. What began as a tech experiment evolved into something far more meaningful, an experience built on human connection, trust, and shared purpose.
The episode explores how the technology worked in both training and on race day, with Clark successfully guided for 98% of the 26.2 miles through live audio support. Along the way, he faced physical challenges, including breathing difficulties caused by his equipment, but pushed through with determination and support from Alastair.
Beyond the run itself, the conversation highlights the emotional impact of the journey, the role of volunteers, and the powerful sense of community created throughout. Clark also reflects on the global media attention the achievement received and the awareness it brought to his charity work with Fight for Sight.
The episode closes with reflections on what’s next, while Clark jokes about retiring from marathons, he hints that future challenges could be on the horizon, especially as technology continues to evolve.
A story of innovation, resilience, and connection, this is far more than just a marathon recap.
