As Big Tim says stretching works well for him, although he is in the minority at not having had a running related injury in 20 years.
Far from feeling silly stretching, although when I see some people strectching I think they realy shouldn't being that.
I hardly stretch at all, but I do warm up for a mile before a hard work out and cool down with a mile jog getting slower all the time & then walk for about 1/2 mile before showering. Even after that cool down & shower I try to stay active for at least an hour before sitting down.
This seems to work for me. One mans medicine can be another mans poison. Whatever you do you can not just run & then go sit down.
Well there's 2 points of view. Good luck & I hope you find what works for you.
