No! It sounds counter-intuitive but you don’t need to stretch before you run.
There’s quite a bit of research indicating that stretching before exercise either does nothing or slightly increases your risk of injury.
It is better to use a dynamic warm-up such as brisk walking, jogging or dynamic stretching. ⠀
You can stretch after you run if you like, but as with a warm up you will probably get more benefit from walking or dynamic stretching.
However, if stretching feels good to you then go for it!⠀⠀⠀⠀⠀⠀⠀⠀
