The Henley Royal Regatta is happening at Henley-on-Thames Oxfordshire. It runs 4 – 8 July 2007 and 2 – 6 July 2008.

From the official site:

Henley Regatta was first held in 1839 and has been held annually ever since, except during the two World Wars. Originally staged by the Mayor and people of Henley as a public attraction with a fair and other amusements, the emphasis rapidly changed so that competitive amateur rowing became its main purpose.

In 1851 H.R.H. Prince Albert became the Regatta’s first Royal Patron. Since the death of The Prince Consort, the reigning Monarch has always consented to become Patron. This patronage means the Regatta can be called Henley Royal Regatta.
