I was once with a mate of mine on a rail tour in Europe.
One stop was Venice. We were walking around town, it was the middle of winter and few people around.
A Jogger ran past us on his jogging business, and the two of us, although not being dressed for the event (Leather shoes and leather jackets) decided to follow the guy. (We were in very good shape).
So after some minutes the guy realizes that he is being followed buy 2 strangers that always keep the same distance, and decides to try and shake us.
This accelerated into quite some speedy running, but he couldn't shake us. After some good long leg, the guy was running for his life with no luck at all. We decided to let him go when he frantically ran into a network of small streets, muhahaha
