My dog and I have started plodding round Trossley Park and I have to mention it. It is such a nice place to plod around and all the people I met were really nice. It's not too hilly for a chubby mammal like me although dog and I got very muddy on each occasion! She's supposed to be white but she's ended up black by the time I wrap a towel round her and put her in the car!
I can really recommend this park for running or plodding.
