The 2007 edition of the Tour of Britain stage race was run as a UCI 2.1 category in seven stages starting in London on 9 September and finishing in Glasgow on 15 September. The Tour was extended to seven days for 2007, with the extra day being used to run a stage in Somerset for the first time. Instead of finishing in London as in previous years, the 2007 race started in London and finished in Glasgow, which is using the event to boost its bid to host the 2014 Commonwealth Games.
