Some lovely canal walks around Birmingham, HappyChick.
I spent my teenage years in SE Birmingham, and parents, sister & her family all still live in the area, so have long experience of Grand Union and Stratford Canals in particular. Once over 18 years od age, a beer in a pub on the route became an additional attraction! Have used canals for running training with brother in law, too.
I've also got away at lunchtimes when working at Fiveways and eaten sandwiches while walking along towpaths - more enjoyable to get fresh air, but not enough time to sit & eat then walk, so had to do both at once.
These days, as a park ranger, I have to inform dog owners of zones where dogs must be on leads / under close control / can run free - ensuring a pleasant visit for all, whether adult humans / children / runners / cyclists / puppies / adult dogs etc is our aim. Not good if a puppy or child gets injured, often because they have less experience / are smaller / face nearer dog mouth height than adult humans / bigger dogs, so adult humans must take repsonsibility.
