Hampstead Heath, Dover Cliffs, etc. I have tried quite a few in the past year.
I also know there are plenty of websites with interesting walk routes, but
1) I am looking for something within day trip reach from London.
2) I also don't feel really safe in the outdoors when I go alone
(*sigh* no friends with specific interest of walking outdoors for fitness).
I was ok walking from Folkstone to Dover alone - there were many families and kids around, so something like that which is populated and semi-touristy would be fine.
Any idea where else I could do some walk-intensive day trips around London, and also meet friendly people along the path?
Main purpose of walking: fitness, keeping in shape, as I have some physical problems which limit my activity options to just walking...
