Sometimes the tasks we have at GoodGym, while always helpful to local community organisations, are less strenuous, and sometimes we get tasks which get our heart rates up and working those muscles. Last night was definitely the latter, with not one but two different jobs that required some serious GoodGym power.

But first we welcomed some lovely new runners to the group - everybody please give a big cheer for Holly and Polly who joined us for their very first group run last night!

After a few quick hellos it was off to the basketball court to do our warm up, which featured some manic whistleblowing, side steps, heel flicks and power skipping. With our heart rate up, there was just time for a headcount and a roundup of all the nice things that had happened to us in the last week. There had been some international travel, some personal milestones and more than one good ice cream eaten - what a happy few days!

With Katie feeling poorly (get well soon Katie!) it was George leading the group on a longer run to Clapham Common. This lovely 2.5k run each way has been a regular feature of Lambeth's group runs this summer, and what a brilliant job you've been doing helping to create a wildflower meadow in this lovely space. Last night was no exception, with the crew giving the place a good water and digging over, and also getting a massively good work out at the same time thanks to some hard ground! Sadly this was our final run to the common for this job, but the task owners said that the work you guys have been doing was 'instrumental' in the project.

"They did a little thank you speech for us at the end because we've been involved throughout and provided so much man power" said Alice

Nice work team!

Meanwhile, the second group had set off on a shorter run to the Grove Adventure Playground near Loughborough Junction for a number of jobs at this epically fun spot - which much to our delight featured a climbing wall and adventure playground. Sadly, this space is threatened with closure by the council, but a group of volunteers have taken on the task of tidying up the place so it can be used again for supervised play by kids who don't have access to safe outside space. What a brilliant initiative.

With Freya tackling the huuuge mowing job, there were also a massive pile of branches to saw up, and an even more massive pile of wood chip to spread at the base of the slide. It was action stations almost immediately and half an hour later the place was looking a lot more friendly. Check out the before and after shots! There was even a few minutes left for a little go on the colourful climbing wall.

After a speedy run back with only a tiny diversion (whoops) we got back to the basketball court and the two groups were reunited (...and it felt so good). We just had time to squeeze in a little tabata (TAbata? TaBATa? who knows) before calling it a night. The idea of this session is that you raise your heart rate high enough that you continue to burn calories after you've stopped exercising, while increasing your aerobic endurance levels at the same time. Suffice to say it's a tough work out, but innumerable frog jumps, power squats, plank jumps, burpees and high knees later, we were done. Well done gang.

Next week the lovely John Hunter will be leading you on what promises to be an ace group run to help out the bees before lovely Katie is back from her travels the week after. Thanks for having me Lambeth, it was great to see you!

After thunder and lightening very very frightening during the afternoon, we actually managed to have a dry run come evening in Lambeth. As the last Tuesday of the month we had our Shit Prize of the Month to give out. The lucky winner was Andrew, who finally, finally bought some new trainers. This has made trainer Katie very happy as she feels sad when she looks at his sad, sad shoes. WELL DONE ANDREW.

James KB led a small but perfectly formed crack team 3km through Brockwell Park to the South London Botanical Institute. They had to move some seeds and boy were there lots. They moved boxes and boxes of the stuff in a human chain. And they only got about half way through. Don't panic Botanicals, we'll be back!

Katie led the rest of the group back to Clapham Common, where we were all happy about the rain as it softened the ground for our nearly final round of digging. We removed loads of the turf and wheelbarrowed it over to the park edge. It was hard work and sometimes even two people jumping on a spade didn't manage to get beneath the surface. But after a lot of arm muscles and a serious portion of elbow grease, we left happy to have made such a big dent in it.

After running back to base, we did some nice stretches and then went home. Well done Lambeth!
