Clapham Common Acro Anniversary Jam Group Photo

The Annual Clapham Acroversary Jam

2027 dates TBA

Every year we celebrate our acro anniversary by hosting a free mega-jam on Clapham Common. This year, we're running two events: Saturday 27th July & Saturday 8th August. This is to give everyone an opportunity to join the fun, together.

We offer hours of acro fun, play, picnicing and dance, as well as acro games and FREE community acro classes. Whether you're a complete beginner or a pro acrobat, all are welcome one of the most fun acro events in the UK.

Expect acro yoga, handstands, slackline, dancing, soft acrobatics and more! And as always, we'll be having a patlach style picnic for food, drink and snacks to share.
