86/87 was still the first generation wave of "running boom" runners. The boom happened after Frank won the Munich marathon, then the kids who were kids then ran their fastest in the mid-80s.
Participation rates are higher now, but the level of competition is nothing by comparison. Courses were open to cars again at 25 minutes for a 5K, 45 minutes for a 10K, and after 3:20 for a marathon. A time I ran for a half marathon in 1985, and finished sixth, would have won that same event, on the same course, all but two years since that time.
I had stacks of VHS tapes - full of road races and track meets that were on regular TV non-stop. NYC and Boston, Falmouth, Phoenix, World XC, Rotterdam, Fukuoka.
The shoes we raced in were fast, way better than the Jayhawks and Ohboris that came before, but they still wrecked our legs. We're the ones you might see hobbling around now. Maybe.
