I have little desire to up the running distances, mainly because I already devote about as much time to exercise as I can fit in around work and family life. Extra distance means more duration and at the moment I'm fitting in runs and gym visits after the kids have gone to bed.
Having said that, I did do my first Parkrun today (5k). 28 mins 15 seconds on a fairly hilly route. That's around the 5k times I was getting 5 years ago.
I understand, I'm also a father although I am lucky in that I work from home so no commute and somewhat flexible work hours. However, I had to make sacrifices for training and make some lifestyle changes. I got to bed around 9pm so I can get out the house at 6am to run for example. I don't take a lunch break but sat at my desk working. To make up for lost hours in the week I work at weekends. And yeah, Sometimes I spend a little less time with my kid, but tbh, I sometimes like quiet time away from the family chaos out on the roads.
