Weihen has given you the course, but if you'd like some human interest in the story, here's a translation of Finn路's adventures today, posted on Baidu. Thanks to the team on Baidu as well!
=====
I'm going to recount the leg today, but as one who fails my language exams and who might not be too clear, I seek your indulgence.
1. From Guangzhou Opera House to Chen Clan Temple
It seems like you have to write "星期8小镇" (Eday Town) on your forehead, then perform some taichi. Anyway, it didn't take much time. Margie/Luke had just finished, and Leo/Jamal took their turn... I followed Margie/Luke, then I saw Brendon/Rachel from afar... Margie/Luke found a taxi quickly... Brendon/Rachel hung around asking for directions, so I went up to help. After checking Baidu and sending them off in a taxi, we got into another one to follow... Leo/Jamal stopped our cab wanting us to let them have it, but since we were going to the same place, we ignored them...
2. From Chen Clan Temple to Eday Town
Eday Town is a children's playpen, located at the No. 5 Tarmac of the old Guangzhou Airport... They built a small car. Because we were following Brendon/Rachel and had left Leo/Jamal behind, we kept thinking the latter was not inside. At this time we believe Dave/Connor, Luke/Margie, Brendon/Rachel, and Mark/Mallory were there... (We were surprised when we saw on the forum that Jet/Cord were only now seen at the Chen Clan Temple. They were probably stuck when they dismissed the metro in the morning and took a cab, getting stuck in traffic on the way...) Herbert/Nathaniel arrived later. Mark/Mallory were the first to finish, folowed by Margie/Luke, Dave/Connor, Leo/Jamal, and Herbert/Nathaniel... (We were shocked to see Leo/Jamal. We thought we had arrived before them and didn't see them enter! There didn't seem to be a second door.) Anyway, the last to the Roadblock was Caroline/Jennifer... As we were preparing to leave for the Children's Activity Centre Brendon/Rachel finished up... We found that Caroline/Jennifer had cleverly asked their taxi driver to wait for them... When we left Jessica/John, Joey/Meghan, and Caroline/Jennifer were still at the Roadblock...
3. From Eday Town to the Children's Activity Centre
Teams had to take the car at the Roadblock to the Centre to get their clue. (We saw on the forums that Jet/Cord and surprisingly Caroline/Jennifer had finished the Roadblock, so we guess that the Express Pass had been used...) When we arrived Dave/Connor had just finished and Brendon/Rachel had just arrived. (At this time the forums said that Mark/Mallory returned to Eday Town to get their bag(s).) There was no one to ask for the next location, and we couldn't just run up and ask "Where are you going?", so the lead was broken... We followed the spoiler and rushed to Shamian... and saw the rolled up mat and a bunch of Westerners with cameras. We deduced this was the Pit Stop, but there was still Liwan Lake, so we headed there.
4. Deduction is that there was a Detour at the Children's Activity Centre
The choices were between Liwan Lake and a sauna house. The two were 5min apart on foot. When we arrived at Liwan Lake Margie/Luke had already finished and left to find a taxi, and Brendon/Rachel had just finished... Here there were Leo/Jamal, Herbert/Nathaniel, and Mark/Mallory. The task at Liwan Lake was to kick a shuttlecock, with the aim of kicking it ten times between the two team members... It wasn't long before Herbert/Nathaniel and Leo/Jamal were done, and then Joey/Meghan arrived... (By then the online forums said Brendon/Rachel had checked in in first place...) We watched Meghan/Joey for about ten minutes, who reached the count of eight several times. Mark/Mallory couldn't get it together... Since we saw that someone had made it to the Pit Stop we returned to Shamian, with John/Jessica finally arriving as we left. We got onto their taxi to get to Shamian... The driver told us about the 5min distance between the sauna house and Liwan Lake. Since we didn't see Dave/Connor, Jennifer/Caroline, and Jet/Cord, we deduced that this was the Detour.
5. Pit Stop at Shamian
We arrived to find Leo/Jamal still looking for the Pit Stop, but it didn't take them very long. They placed in seventh. Hence we waited for the last three teams to battle it out... It was during this time that they filmed a few duplicate shots. (I want to say that the racers were all great actors, pretending to be happy, relieved, huggy...) It was a while before John/Jessica and Joey/Meghan arrived simultaneously, but John/Jessica were faster runners than Joey/Meghan. Ten minutes passed before Mark/Mallory arrived...
1. Brendon/Rachel
2. Margie/Luke
3. Caroline/Jennifer
4/5/6. Dave/Connor, Herbert/Nathaniel, Jet/Cord (unsure of order)
7. Leo/Jamal
8. John/Jessica
9. Joey/Meghan
First and last place were separated by about an hour... Heard that the first six teams were very close.
