The Connect2 route from Marple to Chadkirk is of a very low quality, it has no lighting, it has a lose surface so it not safe on a “fast” bike, has bend where you can’t see someone coming and will leave normal office cloths too dirty to use if you cycle in them. (It even has lots of gates that are designed to make it hard for anyone in a wheelchair to use it that goes against the council policies.)
I very glad it was build, as it is nice for a walk into the country site and is used by lots of dog owners, but can in no way be consider as a “transport” option.
Commuting bikes have less suspension then cars, therefore bike tracks should be built and maintained to a higher standard then motorways, if they are to be a reasonable option for commuting. The tacks also needs to be segregated from walkers and dogs, otherwise it is not safe to cycle at a useful speed.
