Breaking Barriers: How Clarke Reynolds Made Marathon History with Smart Glasses

This podcast episode is something truly special. We’re joined by Clarke Reynolds, also known as Mr. Dot, fresh from making history at the Brighton Marathon. Clarke has just become the first blind person in the world to complete a marathon using smart glasses and the Be My Eyes app, an incredible achievement that’s redefining what’s possible in endurance sport. We’ll hear all about how the technology worked, what it felt like out on the course, and the powerful human connections that made this moment so much more than just a race. We’re also joined by his guide runner Alastair Ratcliffe, who was there supporting him every step of the way. So whether you’re a seasoned marathoner or just love a story that pushes boundaries, this is an episode you won’t want to miss.

There are moments in sport that go beyond finish times and medals, moments that redefine what’s possible. This week, one of those moments happened at the Brighton Marathon, where Clarke Reynolds, also known as “Mr. Dot”, achieved something truly groundbreaking.

A World First on the Seafront

Clarke became the first blind person in the world to run a marathon using smart glasses connected to a live assistance app.

“I’ve achieved the world’s first blind person running a marathon using smart glasses connected to an app called Be My Eyes.”

Powered by Be My Eyes and Meta Ray-Ban smart glasses, Clark navigated all 26.2 miles not with a traditional tether, but with real-time support from volunteers across the globe.

Let that sink in: while running a marathon, Clarke was also holding conversations with strangers guiding him remotely.

How the Technology Worked

The setup was simple in concept, but revolutionary in execution:

• Clarke wore smart glasses with a built-in camera and audio

• Using voice command, he connected to a volunteer via the Be My Eyes app

• That volunteer could see through his glasses and guide him in real time

  
  

In training, Clarke connected with different volunteers for every run. On race day, however, a dedicated group supported him throughout. Despite concerns about connectivity, the system worked 98% of the time over the full marathon distance, a staggering success for a live, crowd-sourced support system.

More Than a Marathon

Clarke’s journey wasn’t just physical, it was deeply human.

“It wasn’t just about me… it was about human connection.”

During training and the race, conversations ranged from:

• Everyday life

• Books and films

• Personal experiences of sight loss

  
  

The marathon became a platform for connection, breaking down barriers between the sighted and visually impaired communities. Clarke used the technology in unexpected ways, like asking a guiding volunteer to describe sweets so he could choose one mid-run.

The Challenge Behind the Achievement

Of course, it wasn’t easy.

• Clarke battled rib pain caused by bouncing tech equipment

• At mile 18, breathing became difficult

• He adapted with a mix of running and walking to push through

  
  

Supporting him on the ground was guide runner Alastair Ratcliffe from The Richard Whitehead Foundation, who:

• Managed backup tech and the recharging of the glasses

• Helped regulate pacing

• Even encouraged other struggling runners along the route

  
  

It was a team effort in every sense, from the volunteers on the app to the support on the ground.

The Finish Line Moment when Clarke Reynolds Made Marathon History

After just over six hours, Clarke Reynolds made marathon history, guided in part by a remote volunteer cheering him on in real time.

“No one can take that away. I’ve left a legacy.”

Impact Beyond the Race

Clarke ran as an ambassador for Fight for Sight, raising around £2,700 directly so far, but the global media attention multiplied that impact significantly. His story reached:

• CNN

• BBC

• International outlets across Europe, Asia, and beyond

  
  

The exposure brought awareness, funding, and visibility to vision impairment like never before.

What’s Next?

Right now, Clarke says he’s done with marathons… mostly. “If the tech evolves,” he hints, “maybe there’s another one in me.” For now, he’s sticking to weekly 5k's, running not for records, but for joy, mental clarity, and creativity.

Final Thoughts

This wasn’t just a marathon. It was:

• A test of technology

• A celebration of human connection

• A redefinition of accessibility in sport

  
  

Clarke Reynolds didn’t just finish a race; he opened a door. For many, that finish line is just the beginning.
