This is just my strong opinion but I firmly believe that this season will break the record of having a NEL on a leg that contains a 'Double U-Turn'. This would be the first time, and I do not believe that the fifth leg is not an elimination, it will be.
My personal opinion
Leg 4: Zambia - Non-Elimination Leg with a Double U-Turn (to spice things up)
Leg 6: France - 'To Be Continued' Leg
Originally I thought Leg 9 would contain the next NEL but someone else here reckons it is the Krakow leg (8th leg) as there is yet another 'Double U-Turn' in Leg 9.
Leg 11: China will be a non-elimination leg without a 'TBC', so there will be a final four, but this time there will be a 12 hour rest period between the two legs, unlike the prior two seasons.
When will a second Fast Forward appear? I will guess it will either be Leg 7 (Netherlands) or Leg 8 (Poland).
