This weekend, the largest triathlon in the world will return to the capital for its 21st year.
The London Triathlon event is famed for challenging over 11,000 participants every year to swim, run and cycle to raise money for charity, with some of the city's most iconic landmarks serving as their backdrop.
This year, the money raised will be donated to Great Ormond Street Hospital and Macmillan Cancer Support.
All competitors will swim in the Royal Victoria Dock and run around the London Docklands. The bike route will vary depending on the day and distance chosen.
