Minecraft wiki entry for Beating_a_challenge_map, associated text: I told them for the extra challenge they could set the difficulty to hard, but not hardcore. Some people could make the map like Minecraft Dungeons, and turn mob spawning off, name the mobs, and maybe even add spawners to the mix, with tools that can break spawners, and maybe quicker if they want breaking possible. At the end, you may get a prize or not, it depends on the person making the map.
