Half Marathon Training

So I've started following a 12-week half marathon training plan for beginners. I have more than 12 weeks before my half and I'm not sure if I'm a beginner, but trying to set myself up for success. I've been running for awhile, but very off and on and I haven't done a half marathon in about 5 years. Back when I did do them, I usually averaged 2:40 or more for the 13.1 mile race, so I'm confident that I'll be much faster this year, since for the first time I can break 10-minute miles now.

I'm also struggling with stress, loneliness, etc., and I find I really HAVE to run every day from Thurs-Sun to feel ok. The trainng plan brings some welcome structure to the exercise routine.

I don't always manage to do all the runs each week and have to recalibrate, due to working crazy long hours Mon-Wed, and mainly running Thurs-Sun, but that should work. The goal is 5 runs a week, with 1 longer run. I'm in week 2, so it means that my long runs have only been 4 miles so far. I looked at lots of training plans online, some started with 7 mile long runs, which I can't do yet, I finally found one that seems reasonable.

Since I'm looking for ways to feel more connected to the city where I live, I might volunteer to help organise the half marathon training group. They do their long runs on Saturdays, and I can't really, since I work then. So might be a good opportunity to volunteer to host the same run Sun am. I could still meet new people and I'm very attracted to the idea of working in the health/fitness industry, so this might be good experience? I'm mainly just trying to figure out how I fit into life in Paris.
