If we are talking about the situation as detailed in, for example, Zinn's
Haywire Heart, those cases were the cumulative result of sustained high intensity training over years, or at least it was conjectured. We are talking much lower intensities. I dont think there is evidence that this type of thing is connected with heart issues.
This is essentially an ultra randonneur event. Repeated 400ks. As gone suggests, for people who havent done one the idea of riding 250 miles is insane. But many of us dont even consider 400k or 600k brevets "extreme" events. Doing a month of those does, to me, attain the level of "extreme", but not in the same way as running 150 miles in the desert.
If we are gaging how extreme this is in terms of effort, a better basis for comparison for non-elite athletes might be hours in the saddle.
