Hi Katrina,
It's all a juggling act, we live in an affluent area of Devon but no way could afford all the extras that some can.
So the typical week looks like this... School has a breakfast club so I usually drop the kids off at school at 7.55 and drive straight into work (which isn't close, 35 mins drive on a good day 1 hour 20 on a bad one!). We have 2 neighbours who will take it in turns to pick the kids up when my husband can't, basically we live in a converted barn on a farm in the middle of nowhere, there are 10 conversions and the farmhouse so we do have neighbours. We all know each other really well, they will babysit for free, in return I often invite them over to dinner and Darren is very handy and will fix stuff for them and decorate for them etc...Bloody hippy Devon families huh? 
Darren works shifts so this means he has some time off in the week and will work some weekends, this helps enormously with the kids but the downside is that D and I pass like ships (ha ha I typed shit accidentaly) in the night.
As for training and running the house, I combine training with exercising the dog and usually run in the evenings or at silly o'clock in the morning. I'm not apprehensive of running on my own in the dark, I don't think you can live your life on 'what ifs'. As for the housework, good job I'm not house proud! That is last on my list of priorities.
One thing I have learned is that we have to be really organised as life is so busy now. We share Google calenders online and if it's not on the calender, it doesn't happen.
We are lucky that it's so safe where we live, I'm fine for my neighbour to get the kids from school and then go back to here house and leave the kids home here. There is always an adult around and the kids know who to go to if needed.
It's all tiring but I wouldn't swap my life for anyone else's, I do have a lot of blessings to count.
The other thing in the mix is that I get bouts of clinical depression, but I have strategies (good and bad, but getting better) to cope with that. After 41 years I recognise the signs.
