Based on this, I believe this is how it went out:
Leg 10: Singapore > Baclaran Church (Route Info) > Rosario, Cavite (Detour) > Intramuros (Pitstop) They stayed here from night June 20 to morning of June 21.
Leg 11: Intramuros > Binondo (Detour) > Los Angeles
I hope they visit one more place in the Philippines before going to US, like what they did before when they went to Palawan.
UST might be somewhere in there. Some have speculated UST was the Pit Stop for Leg 10 with maybe some kind of task near there, which is why Maya would be alone crying. Just speculation of course. UST was the Pit Stop for TARPh1's first Leg. Intramuros is 100% the Pit Stop for Leg 11.
For this penultimate Leg, it seems Binondo is the Road Block since the Instagram photo had four team members waiting at the clue box.
There was a clue box at Rajah Sulayman Park or in front of Malate Church with the pedicab task, whatever that was, happening in the area and maybe as far as Rizal Park which is a couple of blocks away.
That sighting of loading the jeepney though. Maybe the Detour was choosing between loading a jeepney and a tricycle?
