London’s hottest sporting event takes over the capital this weekend, with a record-breaking 59,000 runners set to race in the 2026 edition of the London Marathon. Whether you’re taking on the 26.2 mile challenge yourself, supporting a loved one or simply planning to bring some feel-good spectator energy, knowing where to position yourself can make all the difference – both for capturing a frame-worthy shot and for swerving the crowds.
To determine this list, we’ve analysed millions of customer photos using a data science-led approach to pinpoint the locations that Popsa users loved at the London Marathon in 2025. We’ve excluded Greenwich Park, Blackheath and St James’s Park as these serve as the race’s start and finish points respectively. Canary Wharf claims the top spot, its soaring skyscrapers providing a striking backdrop, while the Cutty Sark and Tower Hill draw crowds for good reason with their historic landmarks.
For those keen to avoid the busiest areas, we’ve highlighted a handful of quieter locations – including spots north and south of the Thames – that saw far less photo activity on race day.
