The London Landmarks Half Marathon is a closed-road, central London event and the only half marathon to race through both the City of London and the City of Westminster. Runners experience a route like no other, weaving past iconic landmarks and hidden gems, from cultural icons to quirky corners of our historic capital. Since launching in 2018 with charity at its heart, the LLHM has raised tens of millions of pounds to support Tommy’s and over 700 other vital causes. Thanks to the generosity and dedication of participants, volunteers, and partners, 2025 alone marked a record-breaking year featuring 20,000 runners, over 700 charity partners, and an unforgettable finish near Trafalgar Square. But LLHM is more than an inspiring run, it’s a celebration. Our race days are brought to life by immersive activations, historical storytelling, and the sounds of London, from samba rhythms to gospel choirs creating an amazing atmosphere at every turn
