Banjo, a few more thoughts for you.
The four stretches I do are:-
- back leg calf stretch, leaning against a wall with back leg straight and heel on the floor
- front leg calf stretch, with front leg bent and other leg off the floor
- hamstring stretch, on your back with leg raised, hands clasped behind knee, then leg staightened and ankle slowly flexed
- quad stretch, stand on one leg and bring heel of other leg up behind buttock, clasping ankle with free hand, hips forward and knee pointed at the floor.
There are two stages to the stretch. You need to hold the extension for 20-30 seconds, then relax for a few seconds, then take up the extension again and
gently extend it - the "development stretch".
There are right ways and wrong ways to do these stretches, so have a look at a trusted website or speak to your physio. I still use this

One other point. The advice used to be to stretch
before exercise, but that only works if your muscles are fully warmed up first. Those of us who are not professional dancers or proper track athletes are much better doing the stretches at the end of a run - I have had no muscle twinges since I moved to that.
