I would imagine that stretching is all over the place. Some say its good to stretch before and after and some say otherwise for various reasons.

The thinking is about how it is done and for what reasons.

I would think younger riders would tend to go without it because they see no tangible benefit or any kind of difference, with our without.

Older riders who already experienced injuries, the aging body with less than optimum intensities of their youth, would look to stretching as a way to prolong the inevitable.
