Here's an update on this topic.
A friend and I were riding home along a large street here in San Francisco and there's a wide tree covered jogging lane off of the side of the street.
I noticed a group of about 12 young men (probably in their very early 20s or possibly late teens) were out jogging in some kind of group run. All of them were in 1980s vintage running shorts.
My guess is they were part of a track and field team from a nearby college or a high school. Where ever they came from, it was great to see the traditional running shorts back in style.
