I see off the injuries listed here are due to improper warm-up, and stretching.
What sort of shoes are you people running with here? I know for me, I run a lot, the best shoes I've come across are Nike Free. They are great for allowing my legs to do the work, and not rely upon expensive shoes that wear out too quick to take up the brunt of the work.
As for injuries related to running, I only get swollen knees, but that's more due to the nature of my job than the running itself. I'm often jumping from high vehicles, and landing flat footed with only a little bend to my knees.

No such thing as "only a 5k". How many other people do you know who can run 5k? Good luck with it!
I run about 5K everyday. It's not hard once you are used conditioned to it. In fact your pace it what determines the difficulty, and for me anything slower than 12Kph is grueling and causes shin splints. Anything faster, and I'm starting to get into my cardio burn zone, and then I start to sweat out a lot..
Cramping is caused by insufficient electrolytes, or rapid loss of them. That's a sign of poor diet for said activities. You may also be drinking too much water, and washing the electrolytes from your system, which is equally bad.
I'm not a pro-runner, but it's part of my job to be able to run decently. There's people here with me that can run at a faster pace that me for much longer. We're talking like a 14-15Kph pace for around 8K. I'm converting all of this from miles, so keep this in mind if my number's seem a little off.
