Gladiating is a fun version of the ancient Roman military combat as was seen on US and British TV Programs from the 1990s onwards.
Various types of combat or adventure-like tasks are engaged in by teams of players.
There are a couple of venues in Ireland where people can engage in Gladiator Weekends:
Adventure Park (Watergrasshill, Co. Cork): https://www.adventurepark.ie/
Team Building Ireland (Kippure, Blessington, Co. Wicklow): https://teambuildingireland.com/corporate-family-fun-day/
