[1][2] He is also a two-time Olympian, and a six-time Italian national wrestling champion for the heavyweight category.

Timoncini qualified for the 96-kg category in men's Greco-Roman wrestling at the 2008 Summer Olympics in Beijing, after placing fifth at the 2007 World Championships in Baku, Azerbaijan.

Because his second opponent advanced further into the final match, Timoncini automatically qualified for the first repechage bout, where he was defeated by Kazakhstan's Asset Mambetov, who scored a double reversed exposure for the entire period, finishing in tenth place.

However, he was eliminated in the first round, after being defeated by Armenia's Artur Aleksanyan, who eventually won the bronze medal in this event.
