I have my Own Place

The TCS London Marathon 2025 will take place on Sunday 27 April 2025

Join Team DUK for the world-famous London Marathon in 2025. The now iconic route takes you past London's most memorable landmarks, including Tower Bridge, the London Eye, Big Ben and Buckingham Palace. With around 50,000 runners taking part and thousands more lining the streets to cheer you on, this really is the ultimate bucket list item!

Although many people run the marathon, others walk it. The good news is the course is flat. And if you have mobility issues or know you’ll struggle to run the whole length, walking is an option. You'll find lots of help in our beginner run-walk training plan.
