Four Goodgymmers rocked up in Totteridge to Grow, the farm by Totteridge Academy. The plan was to see how many of the 32 holes we could dig in 90min for the cement for their new polytunnel's posts.

Each hole needed to be 50cm square and 60cm deep. I foolishly suggested we aim for 4 holes each. We got stuck in - Alefiya, who joined us for the first time, plus regulars Subham and Kubilay. Grow had a team of 3, as Chris, the farm manager, was busy with a family event at the other end of the field.

We started by measuring out and setting the posts (which promptly had to be readjusted) with sledgehammers. Then we took up spades and started digging. And found out just how hard digging 60cm holes actually is! One spade down and we were through topsoil into clay. One side of the clay was full of flint, and dry. The other side wetter, so heavier. An excellent workout, but we only put a small dent in the overall work, between the seven us only digging around 9 holes.

We all stayed past the 90min mark to try and do as much as we could, and the Grow team will carry on digging a few more holes this week, but they've asked us if we can come back next weekend for another round.

Sign up here for next Saturday!

It's a great area to visit - near the Dollis Valley Greenwalk and some nice routes through the back of Woodside/Totteridge. Well worth a Saturday run or cycle!

This morning several brave GoodGymmers travelled from Hackney, Tower Hamlets, Camden and Barnet to help the team at GROW in Totteridge.

In the lovely soggy field and with the rain falling, we had a 4 step process to attack:

1. Dig a trench
2. Create a hole for the whip ( a baby hedgerow - always learning with GG)
3. Plant the whip
4. Cover with woodchip - a GoodGym classic

After an hour and a half or so later our section of the trench was complete. So we said goodbye to Sarah who leads the project and she said she would love some help from Goodgym in the future, so watch this space as it is such a great project to be involved in.
