That is really sort of thing you should not do.

I guess you can walk most of marathon, marathon distance is not some kind of unachievable hike. But as of actually running it, you should not and would not manage to run.

If you pick the right pace, most healthy individuals can run half a marathon. Your knees will explode, you may get injured, but you can do it.

Ok, I took the whole "your body is likely to get damaged forever" thing as "can not and should not run".

And also, healthy non trained individual wont run half marathon. May walk majority of it, but wont be able to actually run that distance.

I ran a half marathon on sand with no training, find a pace you're comfortable with and stick to it. Knees were fine, delayed onset muscle soreness the next day was extreme but passed. (had I not had to turn back because of a river mouth I would have gone further)
