What is your pre/post run look like?

If you feel you need to, look into dynamic stretching. I'm guessing if you do the same stretches before and after, you're performing static stretches before. That can actually promote injury rather than prevent.

This , There's been a lot of research over the past decade that have shown that static stretches can cause injury.

I just walk half a KM before I run and roll my shoulders and neck a bit. Before a race, I'll do butt kicks, high knees and jumping jacks.
No stretching until after the run though.

For reasons noted above, I don't do static stretching before hand. I usually do a 5 minute or so brisk walk...maybe throw some high knees and heel kicks in there or something. I also cool down with a 5 minute or so walk and do a bit of static stretching, but honestly probably not as much as I should...

I hop on the treadmill and run.

Then when my run is over I hop off the treadmill and hit the weights.

I don't do any pre or post stretching and have never had any issues.

I don't do squat. I walk out the door and start running, but I take the Kenyan approach. I start out super slow and easy. My first mile may be a minute or even two slower than my easy run pace. I let everything warm up gradually. It usually takes about 2 to 3 miles before everything starts to feel right.

Post run, I stop running, drink some water and eat like a black hole.

All I do is wake up, bleed the lizard, shove down a banana and toast and head out the door. Never stretch or warm up.

I personally never stretch. Plyometric warm ups.

Actually, I have never heard that static stretching before athletic activity promotes injury. What it does do, and why serious athletes do not do dynamic stretching prior to activity, is that it interferes with performance. Your muscles are something like 10-40 percent weaker for about 20-30 minutes after static stretching.
Some researchers have speculated that the diminished strength associated with static stretching may make someone prone to injury. But it has never been definitively demonstrated.
Whatever the exact percentage is, the diminished strength is appreciable. So now, most serious and informed coaches recommend dynamic stretching prior to an activity -- stuff like easy jumping jacks, crab walks, high knees -- to warm up.
Static stretching can be done afterwards. I like to do it and think it is an important part of my conditioning. But, know this, research has never shown that stretching prevents injury. In fact, many experts who have examined the evidence say that they no longer spend much time stretching. (I suspect they just have not been able to demonstrate it; but I am convinced that someone who is more limber is less prone to injury, and stretching enhances limberness -- over time.)

I walk a few minutes before I run and start off slow on my run, and then I walk after my run. If it was a race, I make sure to keep walking for a good bit after to attempt to prevent my muscles tightening up. During all this, I watch and laugh at all the serious runners doing ridiculous stretches.

Look harder. There are several studies out there. In fact, they even studied people who already stretch before running, and people who don't. They discovered: People who change their pre-workout routine get injured. So, if you already stretch, keep stretching. If you don't stretch, don't start.

If you REALLY want to prevent injury from running, incorporate strength training to strengthen the muscles and tendons that keep your form strong. If your running form is good, and stays good while you run, and you don't overuse your body, your chances of getting hurt from running are SMALL.

Summing up:
1. Don't change your warmup routine.
2. Get good, strong muscles by incorporating strength training.
3. Don't overuse your body. (gradually increase distance over time, rest if you're tired.)

I run first thing in the morning on an empty stomach (just a sip or two of water because food and too much liquids give me cramps). I walk 2 minutes to the sidewalk/trail, then just start running. Same thing with cooldown...walk the 2 minutes from the trail to my house.
