Hallo, in July and August 2024 there was a group of runners, mostly -but not only- clad in black, training at the Flevopark. The group was between 4 à 10 (varying) persons large, and trained at the unusual time around 1600-1700 hrs (which is a bit on the early side) mainly at tuesdays and thursdays. Within two months the group gradually evaporated into thin air.
Who knows who they were? (my guess: uva/hva/auc students). All info is very welcome.

I was the guy on the bicycle (Yes, that could nail me down, even in A'dam)
