12 - 16 September - Will conditions be favourable for the athletes swimming, cycling and running around Hyde Park in the triathlon? Check the forecast.
Athletes will swim in the Serpentine in Hyde Park before completing a seven lap cycle taking in some of London's most iconic tourist attractions, including Buckingham Palace and Wellington Arch. Competitors will then finish the triathlon with a three lap running course alongside the Serpentine.

Jonathan Brownlee won the 2012 ITU World Triathlon in Auckland, while his brother 2012 Olympic gold medallist Alistair Brownlee had previously won the 2011 ITU world title after winning the Grand Final in Beijing. Both Brownlee brothers have competed in the events leading up to the grand final so no doubt they will both be competing to be win this year.
Great Britain's Helen Jenkins won the 2011 World Triathlon Series, however this year Great Britain's Jodie Stimpson and Non Stanford are the ones to look out for as both have already taken a gold in a series event in the lead up to the final.
While these World Championship races require athletes to qualify via their home federation, the Open Age Group Races on 14 September are open to everyone. For more information please visit the ITU World Triathlon website.
Athletes will be hoping the Great British weather is favourable for the triathlon events. Light winds and overcast conditions are preferable for triathlon events however a tail wind will assist athletes when running and cycling.
