On the River Thames there are a number of boat races every year and these have become very popular with the public. Perhaps the best – known of these races is the University Boat Race. This takes place just before Easter every year and is a competition between teams from the Universities of Oxford and Cambridge. They row from Putney to Mertlake, a distance of about four and a quarter miles. This race has been taking place almost every year since 1829.
