Ken,
There is a commonality in the UL hiking and backcountry running, the desire to go very light. This is ok for the ultra distance backcountry runners if they are supported. However, if they choose to go on these long runs without support, as these two did, they are obligated to take enough clothing and gear survive a night out in the conditions they expect to encounter, no different than any other hiker/runner in the wilderness. They did not and hit the free to them helicopter ride button putting others at risk.
