Can We Cross the UK's 2nd Largest City Without Using a Single Road?

Back in April 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. With more people, more security, more filth and sewage and some of Birmingham's most knife crime ridden housing estates, this one promised to be a serious step up from the already challenging Black Country Mission from back in 2021. There had to be slightly more leeway whilst crossing roads this time, but some of the shit we had to go through more than makes up for that I reckon.
