Maybe teams went from Europe to Nepal to Qatar and now South Africa. Probably leg 11 occurs in Latin America (like the last two editions have) and then final leg in the USA.
OMG, is Nepal confirmed!? One of my Wish List destinations!
IMO, Roughly speaking, if they did not to choose to circumnavigate the globe, and going back westward instead, I'm thinking after South Africa, they'll headed to northern part of the continent (Ghana, Ivory Coast, Marocco, somewhere there..) or make a trip all the way up to UK.London, or Dublin, Ireland..
If they did northern africa, the closest gateway to be the finisih line is either Florida, or somewhere in the southeastern coast of USA, and if they plan to go to London/Ireland they'd probably ended up in Vermont or even New York, somewhere northeastern coast...
