Agree, at our (schlem and me) age that's got written injury all over it. Only manage one longish run a week. Then two others 5k max. I'd be ****ed otherwise.
10k a day, every day is ridiculous imo The other half is a runner and does 5k every other day on the treadmill, so is doing 15-20k per week.
I've never done 10k in my life. I once did 3 miles when I was sixteen training with my local Northern league juniors team and I nearly died. Had flashing lights and stars and **** in my eyes. Never again. Football is all about sprints. Was **** hot at them.
