This week 13 GoodGym-ers ran 5.7km to help Muswell Hill Food Bank weed, vacuum, mop and wipe.

We started with a few warm up drills along the side of the Phoenix that I learnt from the NBMCR middle- and long- distance coach Steve Vernon at the New Balance HQ last week. Nicola was a pro at these straight off the bat!

With our legs all warm and our numbers all counted, it was time to head off towards Muswell Hill. Hazel kept me company leading the pack, while Chris was our trusty back-marker.

On arrival we were greeted by Aimee and Deborah, who dished out the tasks before everyone got to work. We had an outside team weeding the patio, an inside team vacuuming and mopping the floors, a window team wiping the windows and Sarah was a team all on her own cleaning doors.

While all this was going on, a couple practiced their wedding dance inside. Deborah treated us to some bananas.

Once all the working was out of the way, it was time for a few strength drills. Walking pause lunges to improve balance, core stability and single-leg strength, bear and crab crawls to improve core, quad, glute and shoulder strength, and kicking squats - again to build that single-leg strength. Running is a series of single-leg jumps, so you really ought to make sure both legs are holding their own if you want to avoid injury, run faster or ran further.

We then ran back to base, with Nicola helping me lead the way and Freya our trusty back-marker. With Chris and Shawn hot on our tails we ended up running up the hills faster than we ran down them on the way home, which made no sense but was fantastic for everyone's legs and lungs and general levels of awesomeness - so good job!
