The 2012 UCI Road World Championships took place in the southern part of the Dutch province of Limburg, also known as South Limburg, between September 15 and 23. The event consisted of a road race and a time trial for men, women and men under 23, and team time trials for elite men and women. It will be the 79th Road World Championships. Castelfidardo near Loreto in Italy was also a candidate, but Italy had held the UCI Road World Championships in Varese in 2008. The Netherlands last hosted the Road World Championships in 1998 in Valkenburg aan de Geul and this time it was the seventh time in total that the country has hosted the championships.
The 2012 championships had a number of changes compared to the former editions. A team time trial is set to be reintroduced. This was last competed as a world championship event in 1994 between nations. The reintroduction will see trade teams compete, similar to the Eindhoven Team Time Trial held between 2005 and 2007. The Junior championships will also be on the programme. With the extra events, the championships will be held over two weekends (nine days) and will also include an opening ceremony and a cyclosportive event.
