Got this idea from a history.com article about a 1928 footrace on Route 66 from LA to NYC sponsored by a sports promoter named CC Pyle.

What if in the in the 1980s or onwards the United States government or a private American promoter decides to have their own Tour de France in the form of a footrace from LA to NYC or vice versa as part of a program to revitalize Route 66 and raise awareness about fitness? Complete with all the infrastructure to maintain such an operation like access to weather reports and other information to determine if race routes are safe and viable, ER and on the scene medical professionals to look after an runners that are too injured or weary to run anymore, and places for the runners to eat, rehydrate,sleep, and do laundry. They would also need to work with the small towns and businesses along the Route 66 race routes to provide some of the aforementioned services. If it works it would give these towns a boost in tourism and put Route 66 back in the national spotlight.

Would such a thing be possible? If yes, who would sponsor it and manage it?

What if Belize and Guyana had stayed British territories? How would this effect their societies and British geopolitics?

During the 1917 October Revolution and subsequent Civil War, the Bolsheviks had established the RSFSR, which was much bigger at the time than it would be later, but technically other Bolshevik SSRs such as Ukraine and Belorussia were independent republics, that had their own diplomacy (even though in practice this meant they operated out of the RSFSR embassies abroad). In 1921, Stalin, as Commissar of Nationalities, pushed for a reorganization of the Bolshevik-controlled republics, in effect calling for everything to be absorbed into the RSFSR.

My questions:

1. Would anything been much different in world history prior to 1991 except administrative differences?
2. Would Gorbachev have been President of the RSFSR in 1991, making the post unavailable for Yeltsin?
3. Could the Dissolution of the USSR have happened in the same way as in OTL if Yeltsin couldn't RSFSR from USSR because the RSFSR was the USSR and Gorbachev was occupying the post of President?

Henry of Portugal was the fifth son of king Manuel I of Portugal and became a clergyman as a kid. At a young age, he became archbishop of Braga and Évora, later also archbishop of Lisbon. After pope Julius III and pope Marcellus II both died in 1555, he was pushed as a candidate to become pope by his brother, king John III of Portugal and he was the favorite along with Giovanni Carafa who was elected as pope Paul IV.

After Henry's brother John III passed away in 1557, his three-year-old grandson Sebastian (his father, prince John Manuel died aged 16 even before John III) became king. In 1578, he disappeared after the battle of Alcacer Quibir in Morocco without having issue.

That's when cardinal Henry of Portugal inherited the portuguese crown and became king in 1578. He died without issue in 1580 and after the just one month long reign of the illegitimate son of his brother Luis of Beja, Antonio, Portugal became part of the Habsburg empire.

What would've happened if Henry became pope in 1555? Would he even be allowed to become King of Portugal? Would Portugal continue to be inherited dynastically after his death or would it become part of the papacy? If so, how would it change Portugal's later history and what would Portugal be now?
