Run East launched in January, linking up with a bakery and record shop.
Organiser Tiernán Oliver said it provided opportunities for people to run together and share experiences – even through the “tough slog” of winter.
“It can be cold, wet and windy and when you are getting up excited about the prospect of meeting people at a dedicated time, you are much more committed and motivated,” he said.
“We are meeting new people every weekend. There’s a great community vibe. People are running together at paces that suit them. People don’t feel left out.”
After a few morning miles, runners huddle inside the small bakery, some sitting at stools in the window that has a direct view of the Harland and Wolff cranes.
“The idea of inclusivity and community and feeling you belong to something without feeling compelled to turn up and perform, Run East is for those who want to enjoy the atmosphere,” Oliver added.
