Hi
What's the work you do? that might make a difference to what you feel up to doing.
I'm similar in that I just over 50 and used to do a 38minute 10k / 18m??s 5K. But that was about 10 years ago, and I;m now slower, but, still fairly strong for my size and do other sports as well.
My commute is 5k each way, but I tend to cycle both ways some days and bus in / run home other days, but the run is extended to about 8-9k if I feel good, or just the 5k if I'm tired or need to get home. I'm finding that as I'm standing most of the day I get very tight calves by the end of the day. This makes me feel very heavy legged for running on the way home, so steady state is all I can do. Usually ends up being z2-3 as there is a hill out of work, so that jacks up the HR and it doesn't go down again. All my intervals are done at other times.
I'll also train (20-30 mins max) - either (home) gym session or run or yoga on days I go in when I get up, before I go in. Bear in mind I also tend to only have to do 3 or 4 days a week, but the days are either 10 or 12 hours long and there is NO pattern to them at all. There is a shower at work, but I try not to get sweaty on the way in, as there isn't really time to get a shower as well as get ready for the day. This means cycle rides aren't fast. I'm not really used to nights yet, so those I just cycle and take it easy. This means my training is very opportunistic and not really heavily structured. I simply say, one speed session/ hill session per week for running, one interval session on the turbo/bike and one weights session per week are my aim, but everything else is a bit open.
My wife tends to either get a lift or bus in and then run home every shift, even after nights, but running is about all she does with a bit of yoga and a little bit of strength training when I make her!
We've both been quite tired recently, especially in the month after each c19 vaccination.
