D'oh! I didn't think to mention that I do serious rucking, because I tend to think of that as running, because I actually run when I ruck. Most ruckers don't.

As for injuries, I have some trouble in my right foot that was due to competing in a 12-hour ruck race on a hilly trail, where we did loops in the same direction. That was May 3rd and it's still giving me a little trouble. I had a different injury in my right foot that was giving me trouble for about two years that I think was due to an aged (about ten years old) orthotic causing hard to diagnose problems that were easy to misdiagnose. I think that trouble is behind me.

One day on little sleep, when I was new to bicycling, I went over my handlebars at over twenty miles an hour, landing on my face. That flat out broke a few teeth and chipped / damaged some others. Last month I had to have six of my front teeth removed, probably due in part to the damage they took on that bike accident, although to be fair, when I was in grad school I drank a lot of sugared coke right out of the bottle and ate away much of the enamel on my upper front teeth, so some of my teeth problems are due to simple negligence.

Oh, and I had an inguinal hernia that was probably due to my rucking. I had mesh put in on one side in 2012. I have continued to ruck competively since. I came in third overall at the Bataan Memorial Death March this year in the male civilian heavy (meaning carrying a 35 pound pack or more) division[0].

Thanks for the extended answer (including the other comment). I'm always curious to hear what active people past certain age do to do stay fit. And sorry for digging deeper, but do you do anything special to work around or manage your injuries? E.g. additional exercises/stretching.
