a youtube video with the same essence you shared
BTW i share one tip for the middle aged folks here mindful of performance. How zhun is that for the individuals here i don't know lah, so see if anyone here believes it.
Best not to take any long breaks and more or less maintain that same "routine"....... there can be peaking for races but it should not be radically different from your usual life. eg your normal days you can run 20 mins 5k, better not aim to peak 17:xx or even 16:xx for that 1 special race in the year. I think half and full marathon distances lagi more tricky.
I cant find the other good video from another coach, but this one also captures the bulk of it.
Basically is you'd need to maintain consistency throughout the year and the off period cannot be too OFF and prolonged, coz it takes time to ramp back up. That one has a graph to illustrates things and it's very clear, but i cant find the vid.
This coach even says 5 to 10% training increase in volume per MONTH, not per week.
So best to find something that one can love doing and if possible make a true hobby out of it so that it does not get draggy...... build that routine.
