As a child my great aunt and uncle used to take me to the Royal Tournament every year up in that there London and the highlight was always the Royal Navy Field Gun Competition, possibly the toughest physical competition there was. The competition involves transporting a field gun through holes, over walls and across a chasm in the shortest time possible and was ran from 1907 through to 1999. The film below is from 1997 with the FAA vs. Portsmouth.
P.S. A family story says that one of my relatives participated in the competition sometime between the wars…after watching this and remembering the event itself I think I would struggle to run five feet with one of the wheels today.
