I think there are quite a few apps that might be of use to you. I use Wikiloc, you just tap in the name of the area you are in or a person's name and 'bingo' all the walks, runs, cycle rides, and so on pop up. You can just identify walking routes for example. It's very useful if you don't know a particular area.
To give it a try just download the app, filter to 'runs', put in 'Cosham' and all of my runs will be displayed for you.
You can if you want, map your own trails and you can send them to Skype, etc. I find it very useful when I'm hiking in France, I can post my routes off to Skype friends and my wife and son.
