I attempt to weave my way through the back alleys, quarries, factories, golf courses, swamps, woods and fields of Aldridge, putting my neck on the line to deliver essential items to my Granddad, Mom and finally Nan.

My aim: to get from Walsall to Dudley (10 miles), crossing the bulk of the industrial black country region without walking down a single road. In doing so I go face to face with a whole host of nasty obstacles, from polluted streams to shopping centre roofs to irate construction workers. Add into the mix a sea of brambles and an unsettling catalogue of spiky fences, and we have ourselves one hell of a pointless adventure.

I convinced my poor brother to join me once more as we made an audacious attempt to cross the entire city of Birmingham, from Sandwell in the west over to Solihull in the East, without using and roads or canals.

Today I finally get to show you my maddest mission to date. A daring raid on a city of 9 million people, 32 vertical miles and countless tall spiky fences. It's Birmingham times 10, and I honestly didn't know if it would be possible going in. A few miles in I was even less sure. But I kept going, and the results are both thrilling and hilarious. Fasten your seatbelts and get ready for the ultimate urban adventure. A tale of endurance, stealth, stress management, but above all conquering fears.
