Also, I want to add that if your knees, toes and/or shins are hurting when you run (short or long distances) you might need to reconsider your running technique, your streching regime and/or footwear.
Running technique, stretching and footwear are definitely important things to be concerned with while running. Unfortunately running in packs in tight formation like in the Army the running technique isn't exactly something you can have full control over.
Then again, certain people are more prone to certain injuries. There may be circumstances in each case, and no matter how you break it down repeatedly banging your shins and knees by running on hard surfaces for long distances is bad for your joints if you have pre-existing problems or a certain body composition.
Here is an article on distance running with prior injuries- http://www.pacesetters.com.my/resource/articles/wc_knees.htm
I'm not trying to say your advice isn't good here, Rush. I think it's important for both sides to be heard out, though.
There are people who's skeletal structure and/or muscular build or general tendon tightness dictate that they should not run distance. This is something that can be overcome by physical therapy in some cases, but for others it's completely irreversible. If someone was training for MMA (since this forum IS named MMA Training) I would say that distance running is easily replaced by another exercise.
The benefits of distance running for those who do have a healthy body composition with no prior knee, ankle, or hip injuries is the building of muscles and ligaments in and around the knee joint for stability. Which is very nice, but again... it can be accomplished by other means as well.
For someone training in MMA I'd always be concerned about leg problems simply because the shins are constantly being worked in a kickboxing environment, and as many of you well know training against leg submissions is always rough on the joints and tendons, too.
