I am in a very similar situation to you, @Pickingmyselfup, although I am a couple of years older and BMI is 26.
I run three times a week (I've run for years but never more than three times a week) and around 30km a week - will hopefully build up to 40/45k weeks in my half marathon prep, but no more. I have hypermobile Ehlers Danlos so never want to push too hard for fear of injury.
I couldn't do more days with sacrificing something else - I like to do a swim and a bike ride as cross-training and do three strength session. I do a short yoga workout at least three times. I don't have kids but I do have horses and spend a lot of time running around after them, plus there's the high needs elderly dog! But I'm happier doing a bit of everything, it works for me.
Over the years, I've never been able to a lot of cardio and lose weight - I used to cycle to and from work for a total of 150 km a week and actually put on weight ... The woman I share an office with got very thin at point (as she said to me herself, I definitely wasn't judging) when she was running five or six days a week, but she is very slim anyway.
I probably run at a similar speed as you (our 10k PBs sound the same) and I'm not sure whether people really realise that this means that long runs can easily get over an hour and a half and everything I've seen on running nutrition indicates that runs over 1.5 hours should be fuelled. It's especially important for women and, ahem, women nearing peri age for bone health.
I have been - at last - gradually but successfully losing weight since October despite training by drastically cutting sugar, i.e., cutting out stuff that's over four per cent fructose sugars (easy enough to check the label), with the exceptions of birthdays, Christmas and New Year's Day to not offend anyone. I take glucose gels on long runs as you don't metabolize glucose the same as with fructose sugars and they don't taste to sweet. It's very hard at first but easy enough once I got into the habit (and broke the addiction - I had a crazy sweet tooth).
Yes, I've only lost 7kg but it's the first time the scales have started going in the other direction in about a decade.
