The streets of London are buzzing as many of the world’s top marathoners arrive ahead of the 2025 TCS London Marathon this Sunday. Among the headliners are legends and rising stars: Eliud Kipchoge, Jacob Kiplimo, Tamirat Tola, Emmanuel Mutiso, and Alexander Mutiso Munyao, all looking sharp as they pose in front of Buckingham Palace.

The field is stacked, with major championship titles, world records, and fast finishes in the mix. With Kipchoge aiming for redemption and Kiplimo pushing to prove himself at the full marathon distance, fans can expect fireworks on the historic course.
