The Big Half 2026

Tower Bridge provides a notable starting point for this race, with the finish near the Cutty Sark in Greenwich serving as a visual goal during training. First held in 2018, The Big Half travels through the "heart of four boroughs" – Tower Hamlets, Southwark, Lewisham, and Greenwich – fostering a strong community atmosphere instead of a formal, quiet event. Expect crowded streets, charity participants, considerable noise, and a course that incorporates some of the same east-London landmarks runners recognize from the marathon. The New Balance Big Relay and Big Mile accommodate teams, families, and those seeking a shorter distance, while participants with disabilities are integrated into the event's structure from the outset.
