You are 100% correct, and some of the other "born to run" cultists are wrong.
So these guys REALLY think that no animal has ever gotten injured running for miles and mile in the wild?? Impossible, right? I mean, they run "natural", that's for sure, with no shoes. But not a SINGLE one of these creatures, when maybe pushing a little too hard (let's say a chase, equivalent to race for us) EVER strained a muscle or injured a tendon, or hurt a bone? As long as their form was perfect? If you really believe that, you've lost your mind.
