In case someone was wondering, I just watched their first "After the Race" special. Yup, you read that correctly, first. Seems it's going to be at least a two-parter.
But it wasn't a full reunion, featuring only 3-teams and a half (half as Jin Xing was hosting). Well mostly featuring 2 of the final 4 (only the entertainers, sadly the athletes were not included) , with the broadcasters being part of a short segment. There are probably more teams appearing on part 2.
It was very Chinese / Asian variety show style, lot's of the live audience interaction, bringing them in to some of the task partial reproductions.
They did recap different aspects of the show, focusing a lot on food, how the sausage speed bump in Germany was designed, discussing the Vodka RI, Paella RI from Barcelona, Wasabi Rolls RI from Tokyo.
Getting a good taxi or good drivers is also discussed and the challenges with language barrier. The subject Self Driving and favorite transportation option is also explored.
The 1st part concluded with them re-trying the ninja rope course from the Japan RB.
