Earlier quoted context omitted.
Seems like you discovered it already, but shin splints, knee problems, back problems, etc. are usually based in either bad shoes or bad form. There are also strengthening exercises you can do for each to make you less susceptible to them. Often times the body's limitations are caused by problems that can be fixed or worked around, allowing you to push yourself farther and harder without hurting your health.
Genuinely curious here. Can you point me to some of these strengthening exercises ?
Note that this is a preventative exercise. Iirc if you already had shin splints this would make it worse. Those with shin splints either swam or biked, but mostly iced and rested. Running was strongly discouraged so that recovery could happen.
