Staring at mountains

Ben Rinnes is the dominating summit of Moray and is a very popular hillwalk. The views, as might be expected, are extremely extensive, taking in much of northeast Scotland. I have yet to venture up but have met a local who recommends running to the top then on to further lesser peaks far beyond. On further questioning he admitted having recently served in an undisclosed military regiment where such runs were commonplace and suggested that he could kill people just by staring at them.
I may well venture up before the summer is out, but at a crawl.
