What do you mean by "finish" the tournament? Complete all 6 levels of your opened provinces or open all 10 Chests? To complete all 6 levels takes planning as there is a 16 hour cool down period until the next level of completed province opens. To squeeze all 6 in the 5 days allotted, you have to get up early and/or stay up late at least one day
Unless of course, you have won a Polar Bear that when fed will reduce the time between levels or have opened the Time Warp Ancient Wonder (chapter 14) which will also reduce the time. If you mean open all 10 chests, that takes 40k points, an average of 1,600 tournament points per person in Fellowship of 25 people. Can you be more specific on what you hope to do?
