Selfie of Sundip out in the countryside

Sundip, aged 37 from London, who has an eye condition closely related to Stargardt Disease, got into running in 2012. Since starting jogging, he's completed a number of marathons and even some ultramarathons.

Inspired to start running  

“I used to be quite unhealthy and didn’t do any exercise. Then in 2012, I started jogging to get a bit healthier and signed up for a marathon with my wife. I’ve run races almost every year since. 

“I try to run at least 1,000km a year, but some years I’ve done 2,000. I go after 50-mile races and double marathons. I just like the idea of doing a huge distance. I've run six ultramarathons and in 2016 I ran four. I also love trail running, through woods and over steep hills." 

Running for a better mindset 

"My blood pressure, heart rate and aerobic endurance have improved so much since I started running. But most of all, my frame of mind has improved. 

"Sometimes I struggle with a negative mindset where I think I haven’t achieved enough in life – but I forget all about that when I’m running. I think I’m generally a happier, kinder person now. There are social benefits too; you meet some good friends through running." 

Goals for the future 

"One of my aspirations is to run a marathon in less than 3.5 hours. I also have a dream of completing a 100-mile race, which takes 20 hours."

Tips for running with sight loss

"For anyone who's visually impaired and taking up running, I’d just try to build a habit – jog for 10 minutes, then walk for 10 minutes each day. The goals will come naturally.

"There can be challenges running when you’re partially sighted. I have blind spots in my vision, so I might not see someone in my path. Once you get out there, you may have a few incidents with people, but you learn to develop resilience to deal with these situations.

"I would definitely recommend joining a running club. Community is so important, and helps to keep you going."
