London Marathon 2026

Every year, around 40,000 runners line up for the TCS London Marathon, ready to take on the famous 26.2-mile course that winds through the heart of the capital. From the Tower Bridge to the London Eye and the Houses of Parliament, runners are cheered on by thousands of supporters, creating an atmosphere that’s emotional, euphoric, and truly unforgettable.
