OP, best of luck with your new regime! Don't let anyone put you off I've been negotiating with myself all day about whether or not to go for a run (it's sooo cold!!) and it's taken your post to remind me that if a beginner & a 12y/o can resolve to religiously follow a plan and inspire others then surely I can drag myself out for a short gentle jog too! Look forward to hearing how your session today goes!
I'm biased because I'm a current member, but I would wholeheartedly recommend Purple Patch Runners! They are a friendly and welcoming bunch - the people who run the club, AND the members - and there is something for everyone. It's perfect if you don't want the pressure of getting together for training sessions, or simply can't do this (as in the OP's case); but equally there is a sociable side that you can get involved in if you want, with meet-ups at specific races and parkruns. There is always someone willing to provide advice and opinions, and they also organise running camps and courses, if you want something a bit more specific. I joined originally *because* of it being "non-geographical" (there are members spread out across a wide area), but have found many other benefits since then, and I know other members who would say similar
