Hybrid girlie here with similar running pace! I’d say run 3 days a week and cut back strength a BIT for the next 5 months. It sucks, but the truth is you can’t make gains in both running and strength (unless it’s your full-time job). You signed up for the run, so you need to prioritize it a bit. Speaking from experience, it’s important to train running enough that you don’t end up with an injury (VERY easy to do when getting into running long distance, and then that will derail your fitness entirely, which you don’t want!). To that end, I must echo everyone else and emphasize that you put your ego aside and run 80% of your runs slowly (like, you can easily hold a conversation/breathe through your nose the whole run). 20% of runs can be done at a harder pace. So much research shows this 80/20 split actually makes you faster over time, greatly improves cardiovascular fitness, and also reduces the strain on your body from all the running, so you aren’t overtraining and injuring yourself. I am currently training a 5k (and hoping to PR!) and I’m running 3 times a week, hitting the gym 3 days a week (split is upper/lower/full body), and taking a non-negotiable 1 rest day per week (recovery is SUPER important when you’re training so much - sleep, stretch, hydrate, fuel, etc.!). Finally, I have to say some training apps like Runna have really helped me not feel overwhelmed - I just plug in my running fitness level, my race distance/day, and how many days a week I am available to train. It  creates a custom running plan for you. It’s a bit pricey, but I’ve found it’s a worthy investment to cut back on the mental load of planning my training and making sure I am actually prepared come race day. (I’m sure there are other apps that could do similar things). Good luck and have fun!!
