Serpentine Running & Triathlon Club

2,000 runners, one lake, and a serious brunch habit

🏃 Westminster Weekly - Wednesdays, Saturdays & Sundays Beginner-friendly Social Competitive Marathon training

Yes, it's big - around 2,245 of us - but that's the secret: with this many people there's always someone running at exactly your pace, and a proper beginners' course if you've never done this before.

We meet at the Serpentine Bar & Kitchen in Hyde Park on Wednesday evenings and Saturday mornings, and over in Richmond Park on Sundays. Group runs go anywhere from 7 to 16km, with track at Paddington and lung-busting reps up Primrose Hill if you fancy them. Affiliated to England Athletics since 1981.

Most runs end in coffee or brunch, there's the famous Last Friday 5k in Hyde Park, and you can come along and try us before you part with a penny. Just turn up.

Real stories of people who found their people in London.

Claire Donnelly · 7 June 2026 I sat silent at book club for months. Finding my voice there changed my whole life. I'd spent my whole life letting other people's opinions fill the room. A monthly book club, and one patient question, taught me that mine mattered too. Rachel Okafor · 15 June 2026 I was someone's mum from 6am to midnight. A book club gave me back two hours that were mine. After my son was born I disappeared into being his mother. The thing that brought me back wasn't a spa day or a grand gesture. It was a paperback and a room full of women. Margaret Ellison · 5 June 2026 At 68, I thought my world had got smaller. A walking group proved me wrong. After I retired and lost my husband, the house went quiet and the days got long. Then a Saturday walking group gave me back something I thought was gone for good.
