Just nice, Coach Parry just release a video on Why we are slowing down as we age. First thing is we have to accept our declining physiology changes. So can't compare with those younger youtuber who are actually above average in talent. It's a reason why I don't watch most youtuber runners and their training to reach simi sub 20 mins 5km. We will never come close in performance with our declining physiology, and at above 50, it is declining at accelerated rate.
I feel Coach Parry's philosophy for training above 50 years old is sound and safe for us. Focus is improving aerobic performance (mitochondria health), Strength Training. Not neglecting high intensity, but really no need for those siong workouts like train for sub 20 min 5km type of training, coz we will never reap the same benefit as a 30 years old youtuber in that same workout and we will burnt out.
Once you accept that, set your own realistic goal base on your last race.
