I have been running for almost 2 years now, after pretty much never running before in my life. I have had the usual injuries (shin splints, sprained ankle, etc.), but nothing serious. I've always thought I was doing everything right, until I saw this video about the day after the marathon:

The thing is, my thighs have never - not once - hurt after a run! My calves have hurt, as well as my feet, hips, etc. So what am I doing wrong? Or am I doing anything wrong at all?
Some sites suggest this could be because I have weak thighs, and the rest of my legs are picking up the slack. But I can comfortably leg press about 3 times my body weight, so I don't think that's the problem.
Is this something to be concerned about? Or is it just marathon specific: I mean, I've never run more than a 10K.
