I'm thinking after the bull racing (roadblock), they do a detour. Either something to do with salt production or making shrimp paste. Then go to Surabaya for pitstop. Next leg either stay in Surabaya or go to Bali, then from there Australia or New Zealand, then Europe.
Other detour options in Madura: something to do with batik, jamu (herbal drink), food or agribusiness (corn or tobacco).
Btw, Madura is very hot & arid. Teams would probably struggle tomorrow
