The event on Sunday at the centre in Green Lanes, Stoke Newington, saw the grand opening of its outdoor climbing boulder park.

The free-standing boulders are low enough for people to climb without ropes, but high enough to still feel quite challenging.

Visitors were also treated to the spectacle of a “dyno” competition, with participants performing a dynamic move to grab a hold that would otherwise be out of reach.

“It is quite a something to watch,” said Kerry Simmons, who works at the centre.

“Generally both feet will leave the rock face and return again once the target hold is caught, non-climbers would call it a jump or a leap.”

The winning jump of 260 cm was performed by Tom Arnold.

Ms Simmons added: “The point is to show the customers and local community what we have been working towards since our commitment to operating as a sustainable business.

“We have won several awards for our efforts and this year and have entered Hackney in Bloom, we offer community plots for local people to grow their own food, and we run sustainability workshops and grow our own food for our cafe.”
