i found this post on instagram earlier today:
lifeofkruoh Just finished filming for "The Amazing Race" yesterday! Had a great time! Tje episode will air in October.
#kruoh #amazingrace #tigermuaythai
he posted this today, so yesterday = sunday.
from his posts, i think he's an owner of a shop in Phuket, Thailand. and as we know, Thailand wasn't on the list of this season's (speculated) destination. so i guess there's a possibility that they add Thailand to their destination's list.
In addition, yesterday Allan Wu posted a picture of pitstop mat on a beach on his instagram story. i forgot to screenshot it, sorry :/ it doesn't mean anything but it could really suggest us that there's a Phuket leg yesterday
