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.
