I am marathon training and finding that the best time for me to fit in my weekly LSR is early in the morning when it is still dark. I live in West London and have a couple of routes, one along the Thames towpaths and another into Richmond Park, that I have been using. I often don't see any other runners and, at most one or two. I recently started running with a head torch which helps me see where I am going but probably would offer little (well, no) protection against attack. What do most people do in this situation? I do not want to have to run long distances on lit pavements as I find the soft trails are quite important to my ability to absorb the longer runs. Thanks for any advice.
