A cracking evening at one of our favourite spots — Hackney Marsh Adventure Playground, which always delivers on the rewarding session front.

We had a nice little group run: Nick, Rue, John, Adam and Brad joined me in setting off from the Aquatics Centre, jogging up the canal in glorious evening light — about as lovely a warm-up as we'll get. We were joined by Chloe, Joke and Paul at the playground, and got a warm welcome from task owner Ange.

For the record: a Newham task, held in Hackney, with Chloe, John and Rue over from Tower Hamlets. Three boroughs, one sandpile...

The task itself? A mound of sand to shift. Not just any sand — this had been donated from the London Stadium long jump pit, freshly dug out after Saturday's Diamond League meet. Our job was to move what we could over to the sandpit part of the playground.

Cue a shifting and spreading production line: shovels flying, wheelbarrows trundling back and forth, and plenty of teamwork as barrow after barrow were ferried across, with only a small number of mechanical and loading issues.

A couple of surprising things - first, that the stadium needs brand new sand every single time — and second, just how much of it there is. But actually when you think about it, world-class long jumpers probably do cover a fair bit of ground, so the pit must need to be pretty deep to land in safely. A quick google afterwards confirmed it: a competition long jump pit needs somewhere in the region of 6–9 cubic metres of sand. Worth retaining that for when it comes up in a pub quiz.

By the end of our session, we'd made a visible dent and felt like we'd had a workout. Huge thanks to Ange for having us. And a brilliant turnout — it genuinely made the difference, because these tasks simply don't happen without people showing up. So thank you to everyone who came along and we'd love to see you all again soon 💪
