To win the 2nd challenge, one has to reach the 1st ring by the end of the 6th day and be the last one on the central ring by the end of the 7th day. Hiding to ensure survival will not work. You will be eliminated when sections of the arena get destroyed so you have to continue moving forward. Some will be lucky to have been teleported straight into the 1st ring so they won't have to face the challenges that come with crossing the map.
