a new theory materialising - to cope with joint problems running in the 50s ...
I am normally attentive to energy provisioning for the longer outings I do on a weekly basis - perhaps 1h30; and when occasionally I getit wrong its normal to persevere and enjoy a bit of hypoglaecemic euphoria.
However ... my back and knees aint what they used to be, and I think I've started to note a tendency - of prolonged recovery after such runs with poor energy finish. So - the theory would be - that if energy levels are positive you can better avoid the heavy plodding phase - in which an elastic step and better posture are no longer available to protect the joints.
Can anyone confirm this ?
