Detroit Marathon: 3 die

@Charlie_Francis

There is a great deal of interest in this topic in recent years. I believe that intervals that vary the heart rate are far superior to steady state runs, which often preceed marathons. as these deaths were relatively early in the marathon, i wonder if these were more related to a pre-race training issue.

I take it from your post that you’d prefer at least the inclusion of extensive tempo (correct me, if I am wrong). Why is that specifically for marathons or any activity >10 K? And how much of it per session or times per week? Thanks!
