We've added some clues along the route, to help you along.
First off, there's the stencils. Same vibe as last time: only on pavements (like the marks roadworkers leave) and other previously graffitied objects.
Then there's some new stuff too.
Norfolk Park is too beautiful for spray paint. So we've gone one step further. We've installed a few Viewpoint plaques, beneath the mad orienteering ones that are already in place.
And finally, keep your eyes peeled at the start of the walk for some familiar faces.
