Addition to the gladiator arena; a gauntlet. You just have to keep on fleeing forward in an endles gauntlet with tougher and tougher warriors beating the crap out of you. The one that gets farthest of a challenge wins. And as with gladiators, there's a list of who has run and how long they came. Idea is to see who can flee and who has the constitution to withstand beating. And make them so tough that you don't want to keep on fighting, killing them and regenerating inbetween them.
