I’ve been running with my dog a lot more during this work from home situation many of us are in, usually around that 10:00 pace range (I let him choose the pace hahah).
You’re unlikely to benefit directly from the runs themselves, but you can certainly use them to your advantage. I recommend two options:
1. Get in your quality workout after running with your wife, later in the day. Go with this option when you feel you would benefit more from working out on slightly fatigued legs (longer runs, tempos, thresholds, etc.). You’ll teach your legs to remain strong while already fatigued, as needed racing a marathon.
2. Get in your quality run in the morning before work, mostly when you need your legs to be fresh. Like when you need have that extra pop for intervals or faster workouts. You’ll receive the regular benefits of your workout, and running with your wife later will provide an opportunity to shake your legs out further after a hard effort, promoting more recovery.
My main advice for both options is to not neglect your stretching and fueling for those wife runs. They may be extremely easy, but you’re still burning calories and stressing your muscles. The runs can be helpful for the reasons I mentioned, but will hurt if you don’t treat yourself right before and after.
Finally, my advice is based on the idea that you’re limited with your time to run during lunch. With bigger times windows, you have more options!
