Many thanks for that link, Ultramarkus. Google is not of much help sometimes on niche topics. (Popularity — "link juice" — does *not* necessarily equal a quality worthwhile informational link, contrary to their algorithm.) I used to follow ultrarunning years ago in the early heyday of the 1970s/80s, and have been back following it again to a point now that it's really burgeoning. Not enough time in the day these days, though, to do everything one might like to do. So much more going on in the sport today, difficult to keep abreast. I'll be bookmarking this link.
